Pls can someone help me factorise this: a²+9a+8
Answer:
(a + 8)(a + 1)
Step-by-step explanation:
We know that the first term is squared, so we can put it out like this:
a * a
The third term has to be separated so that the sum of the two factors is the coefficient of the second term, 9.
8 = 4 * 2 (does 4 +/- 2 = 9? nope, we can't use that)
8 = 8 * 1 (does 8+/- 1 = 9? yes, when 8 + 1)
So the factor is a + 8 and a + 1.
Put this together and (a+8)(a+1)
Isosceles triangle ABC contains angle bisectors BF. AD and CE that intersect at X
136
132
68
44
Answer:
136
Step-by-step explanation:
Bc i took the flvs test and got it right
The triangle ΔXAC formed by the angle bisectors is an isosceles triangle
The measure of m∠CXA is the option;
136°
Reason:
The given parameters are;
ΔABC = An isosceles triangle
BF, AD, and CE = Angle bisectors, intersect at X
m∠BCA = 44°
m∠XCF = m∠XCD Angles formed by angle bisector CE
We have;
m∠BCA = 44° = m∠XCF + m∠XCD; by angle addition Postulate
∴ 44° = m∠XCF + m∠XCF; by substitution property of equality
44° = 2 × m∠XCF
[tex]m \angle XCF= \dfrac{44^{\circ}}{2} = 22^{\circ}[/tex]m∠EAF = m∠XAF + m∠XAE
m∠XAF = m∠XAE; Angles formed by angle bisector AD
∴ m∠EAF = m∠XAF + m∠XAF
m∠EAF = 2 × m∠XAF
m∠EAF = 44°; by base angles of isosceles triangle
[tex]m \angle XAF= \dfrac{44^{\circ}}{2} = 22^{\circ}[/tex]m∠CXA + m∠XCF + m∠XAF = 180° Angle sum property of a triangle
m∠CXA = 180° - (m∠XCF + m∠XAF )
Which gives;
m∠CXA = 180° - (22° + 22°) = 136°
The measure of m∠CXA = 136°Learn more here:

Very quickly pleasee!!! What is the remainder when 3 to the power of 2020 is divided by 30
===============================================
Explanation:
Let's see if we can find a pattern where we divide powers of 3 over 30
In other words, let's see if we can find a pattern for (3^n)/30 where n is a natural number {1,2,3,4,...}
We only care about the remainders so ignore the quotients.
This is the pattern of remainders:
3^1 = 3. When divided over 30, we get remainder 3.3^2 = 9. When divided over 30, we get remainder 9.3^3 = 27. When divided over 30, we get remainder 27.3^4 = 81. When divided over 30, we get remainder 21.3^5 = 243. When divided over 30, we get remainder 3.3^6 = 729. When divided over 30, we get remainder 9.We see the pattern repeating again after we get to remainder 3 a second time. The pattern of remainders is {3, 9, 27, 21} which repeats forever.
The length of this cycle is 4. So what we do is divide the exponent by 4 to see what the remainder is. For instance, both 1 and 5 lead the same remainder when we divide by 4. This tells us 3^1 and 3^5 lead to the same remainder as shown in the pattern above.
Similarly, 3^2 and 3^6 lead to the same remainder. These items are spaced exactly four units apart, which is the length of the cycle.
For the exponent 2020, we get 2020/4 = 505 remainder 0
Having a remainder 0 is the same as having remainder 4, when dividing by 4.
So we'll be looking in the fourth slot of the cycle {3,9,27,21} to see the answer is 21.
Dividing 3^2020 over 30 leads to a remainder of 21.

21,28,35 determine whether the triangle is acute, right,obtuse, or not a triangle.
Answer:
I believe it is an acute triangle but im not 100% sure
Step-by-step explanation:
The triangle with sides 21 , 28 and 35 is a right angle triangle
What is a Triangle?A triangle is a plane figure or polygon with three sides and three angles.
A Triangle has three vertices and the sum of the interior angles add up to 180°
Let the Triangle be ΔABC , such that
∠A + ∠B + ∠C = 180°
The area of the triangle = ( 1/2 ) x Length x Base
For a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
if a² + b² = c² , it is a right triangle
if a² + b² < c² , it is an obtuse triangle
if a² + b² > c² , it is an acute triangle
Given data ,
Let the triangle be represented as ΔABC
Now , the base of the triangle is BC = 21
The height of the triangle AB = 28
The hypotenuse of the triangle is AC = 35
And , for a right angle triangle
From the Pythagoras Theorem , The hypotenuse² = base² + height²
Substituting the values in the equation , we get
35² = 21² + 28²
On simplifying the equation , we get
1225 = 441 + 784
1225 = 1225
Hence , the triangle is a right angle triangle

One day your aunt gave you 20 pieces of candy and you ate 2 pieces each day. After a
certain number of days, there are 10 pieces left. Which of the following equations
represents the day, d, when there are 10 pieces left?
Will award brainliest
Answer:
5
Step-by-step explanation:
on day 1 you had 20 pieces and each day you lose 2 pieces. so that means your equation is y=-2x+20. So x = number of days, and y = pieces of candy. Plug in 10 for y, minus 20 to both sides, divide by -2 to each side. Then your answer is 5.

When we have numbers in parenthesis, we generally want to deal with those first. However, we can hit a rough patch when a variable is in there. Consider this:
2(3 + 4) = 2(7), or 14.
But, the two can also be distributed into both numbers in the parenthesis, like this:
2(3 + 4) = 2*3 + 2*4
That leaves us with the same answer—14! We can apply this to a variable, and that will help us figure out 9(p - 4), or the left side of your equation you presented.
9(p - 4) = -18
9*p - 9*4 = -18
9p - 36 = -18
Add 36 on both sides to isolate the variable (in this case, p)
9p = -18 + 36
You can also write it like this; 9p = 36 - 18
9p = 18
Divide 9 to isolate p
p = 2
So, we would get (p = 2). Make sure to practice a few more questions like these to really get the hang of it—you'll be using this a lot in the future!
Good luck!

James read an equal number of pages of his book each night for 8 nights to prepare for his upcoming exam. During this time, he has read a total of StartFraction 6 Over 7 EndFraction of the book. What fraction of the book did he read each night?
Answer:
3/28
Step-by-step explanation:
James read an equal number of pages of his book each night for 8 nights to prepare for his upcoming exam.
The total fraction of the book he read in 8 nights = 6/7
Hence,
8 nights = 6/7
1 night = x
Cross Multiply
8x = 6/7 × 1
x = 6/7 ÷ 8
x = 6/7 × 1/8
x = 3/28
Therefore, every night, the fraction of the book he has read is 3/28
