Question 40 and it about adding and subtracting polynomials
kolbaska11 [484]

Answer:

39x-7

Step-by-step explanation:

The perimeter is all the sides added together so

9x + 8x - 2 + 5x + 1 + 17x - 6

Since you can't solve it you just want to simplify the equation, add the like terms together

9x+8x+5x+17x = 39x

-2+1-6 = -7

Your equation is 39x-7

Solve by elimination:<br> 4x+9y=28<br> -4x-y=-28
nikdorinn [45]

Step-by-step explanation:

4x+9y=28

-4x-y=-28

8y=0

divide both side by 8

y=0

solve for X in equation 1

4(X)-9(0)=28

4x-0=28

4x =28

divide both side by 4

4x/4=28/4

X= 7

y=0,x=7

Can someone please help
ruslelena [56]
You can find the answer by substituting the x-values provided in the question and seeing if you get what the question says.

a satisfies all of the parameters.
b doesn’t satisfy g(-1), so it’s not b.
c doesn’t satisfy g(-1), so it’s not c.
d doesn’t satisfy g(-1), so it’s not d.

The correct answer is a.
