Which sum or difference is modeled by the algebra tiles?

A.
(x2 + 4x − 2) + (x2 − 2x − 4) = 2x2 + 2x + 2
B.
(x2 + 4x − 2) + (x2 + 2x + 4) = 2x2 + 2x + 2
C.
(x2 + 4x − 2) − (-x2 + 2x − 4) = 2x2 + 2x + 2
D.
(x2 + 4x − 2) − (-x2 − 2x + 4) = 2x2 + 2x + 2

1,150 give brainliest

step-by-step explanation

2r= 2300

r =1150

sine

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
