Factor the polynomial
Art [367]

Find the GCF (Greatest Common Factor)

GCF = 2x

Factor out the GCF (Write the GCF first and then, in parentheses, divide each term by the GCF.)

2x (2x^3/2x + 4x^2/2x + 6x/2x)

Simplify each term in parentheses

-2x(x^2 + 2x + 3)

<u>Answer D. -2(x^2 + 2x + 3)</u>

Solve the system algebraically. Check your work.
Luden [163]

answer.

Answer:

x=2 and y=0 is the required result.

Step-by-step explanation:

We have been given system of equations:

5x+2y=105x+2y=10     (1)

And 3x+2y=63x+2y=6      (2)

We will use elimination method:

Multiply 1st equation by 3 and 2nd equation by 5 we get:

15x+6y=3015x+6y=30      (3)

15x+10y=3015x+10y=30      (4)

Now subtract  (4) from (3) we get:

-4y=0−4y=0

y=0y=0

Now, put y=0 in (1) equation:

5x+2(0)=105x+2(0)=10

5x=105x=10

x=2x=2

Hence, x=2 and y=0

Simplify the expression where possible. (t 9) -8
makvit [3.9K]

Answer:

\frac{1}{t^{72}}.

Step-by-step explanation:

To solve this problem, we need to simplify the expression (t^{9})^{-8}.

We know that (x^{a})^{b} = x^{ab}

Therefore:

(t^{9})^{-8} =t^{-72} =\frac{1}{t^{72}}.

I need help with these 2 problems I cant figure out.
Alla [95]

I started by labeling the right angle (Angle C) 90º. Next, I wrote down everything in one equation.

2x + 90 + 3x - 20 = 180º (180 degrees in a triangle)

Next, I add 20 on both sides.

2x + 90 + 3x = 200º

I combine like terms (2x and 3x)

5x + 90 = 200º

I subtract 90 from both sides.

5x = 110º

Divide 110 by 5 to get x.

x = 22

======

For problem two, I label all the angles I know.

49º + 80º + r = 180º

I add 80 and 49.

129º + r = 180º

I subtract 180 and 129 and get 51º, which is your angle for R.

For angle X, you know that angle R plus angle X equals half of a circle, which is 180º

We know from before that 129º is 180º without R, so X is 129º

I hope this helps! Let me know if I'm wrong!
