Answer: -1410

Step-by-step explanation:

Let's start by subbing in -4 for x

$-4x^4 - 3x^3 - 29x^2 - 114\\-4(-4)^4-3(-4)^3-29(-4)^2-114$

Now we can solve

$-4(256)-3(-64)-29(16)-114\\-1024--192-464-114\\-832-464-114\\-1296-114\\-1410$

Is the product of -5 +x and x+4 equal to the product of 5+x and x-4? Explain your answer.

beks73 [17]

Let's find out!

-5 + x * x + 4.

-5 + x^2 + 4.

-5 + 4 + x^2.

-1 + x^2.

5 + x * x - 4.

5 + x^2 - 4.

5 - 4 + x^2.

1 + x^2

So, they are NOT the same, because one of the "1"'s are negative, and the other is positive.

5x + 2y =12<br> - 6x - 2y = - 14

lord [1]

5x + 2y = 12
-6x - 2y = -14

Add them
-x = -2
x = 2

5x + 2y = 12
(5*2) + 2y = 12
10 + 2y = 12
2y = 2
y = 1
