≤ (less than or equal to) or ≥ (greater than or equal to) have solid lines because it can be equal to.
< (less than) or > (greater than) have dashed lines because it cannot be equal to.
Less than ( < or ≤ ) = shade under.
Greater than ( > or ≥ ) = shade over.
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

Step-by-step explanation:
Happy to help.
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!

Complete Question
Which expression is equivalent to 10 - 8?
Answer:
(Choice A) 10 + (-8)
Step-by-step explanation:
Which expression is equivalent to
10 - 8?
Comparing the options
(Choice A) 10 + (-8)
The rule = + × - = -
Hence
10 + (-8)
= 10 - 8
Choice A is correct
Choice B) 8-10
8 - 10, Choice B is incorrect
(Choice C) 10-(-8)
The rule states that:
- × - = +
Hence,
10 -(-8)
= 10 + 8
= 18
(Choice D) -8-10
-8 - 10
= -18
This is incorrect.
Choice A is the correct option which is the expression is equivalent to 10 - 8.

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
6(2 + x) - 4 = 8x true?

Vector u has initial point at (3, 9) and terminal point at (–7, 5). Vector v has initial point at (1, –4) and terminal point at (6, –1).
What is u + v in component form?
⟨-10, -4⟩
⟨-5, -1⟩
⟨3, 9⟩
⟨5, 3⟩
Answer:
⟨-5, -1⟩
This is the right answer Edge 2020
Step-by-step explanation:
U + v in the component form will be -5 [tex]\hat{i}[/tex] - [tex]\hat{j}[/tex] hence, ⟨-5, -1⟩ will be the correct answer.
What is a vector?An item with both magnitude and direction is referred to be a vector.
A vector can be visualized geometrically as a straight spline, with a pointing in the orientation and a length equal to the value of the vector.
Geometrical objects with magnitude and direction are called vectors.
A line with an arrow in its direction can also be used to represent a vector, and the length of the line relates to the vector's amplitude.
Given that a vector initial point at (3, 9) and terminal point at (–7, 5). Vector v has initial point at (1, –4) and a terminal point at (6, –1).
So vector A = -10[tex]\hat{i}\\[/tex] - 4[tex]\hat{j}[/tex] and B = 5[tex]\hat{i}\\[/tex] +3[tex]\hat{j}[/tex] now vector joning by this two will be AB = -5 [tex]\hat{i}[/tex] - [tex]\hat{j}[/tex] .
