Write an equivalent expression by applying the distributive property (x + y + 3) x (y + 1) = A: 2y2+xy+4 B: 2y + x + 4 C: y2+xy+4y+x+3 Please help math makes me go insane

C

Step-by-step explanation:

So we have the expression:

To multiply, use the distributive property. Multiply (y+1) to each term on the left:

Distribute the variables:

Rearrange them to combine like terms:

The correct answer is C.

Edit: Typo

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.

answer: 12x^2+6x

step-by-step explanation:

6x does not equal 24x. hope it works!
