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)

===============================================

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:

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.

Answer: x = 20

Step by step explanation:

Let's say that "___" = x to get rid of confusion when solving.

The new equation is 10% of x = 2.

Let's rewrite 10% as 10/100 and "of" as the multiplication sign.

10/100 * x = 2

Let's simplify 10/100 as 1/10 by dividing it by 10/10 which is one(there is no change in its value, it just makes our job easier.)

1/10 * x = 2

We can now multiply both sides by 10 to get x = 20.

Let's check: 1/10 * 20 = 2, so it is correct.

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.

Answer:

x = 150

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides

Here n = 6 , then

sum = 180° × 4 = 720°

Sum the given interior angles and equate to 720, that is

130 + 90 + 120 + 112 + 118 + x = 720, simplifying

570 + x = 720 ( subtract 570 from both sides )

x = 150

Answer:

  285 centiliters

Step-by-step explanation:

Using the given conversion factor:

  1 quart = 0.95 L = 95 cL

  3 quarts = 3 × 95 cL = 285 cL

There are approximately 285 centiliters in 3 quarts.

__

Centi- is a prefix meaning 1/100th. So, 0.95 L (95 hundredths) is 95 cL.

Answer:

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

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

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°
