Should be A. 12.3x12.3 is about 6x25
Answer:
First is 
Second is
Step-by-step explanation:
Open up equations and do FOIL method.
First equation:
(x + 2y)(x + 2y)
x^2 + 2xy + 2xy + 4y^2

Second equation:
(y + 2x)(y + 2x)
y^2 +2xy + 2xy + 4x^2

The answer for that question is 1 3/5
Answer: B
(2x + 6)^2 can be rewrote as (2x + 6)(2x + 6).
Multiply out to get 4x^2 + 24x + 36
Answer:
For x=2, the expression 4(5x-8) will be 4 more than the expression 2(4-x)
Step-by-step explanation:
Given expressions are;
4(5x-8) and 2(4-x)
For 4 more than the second expression, we will add 4 with second expression.
4(5x-8) = 2(4-x) + 4
20x - 32 = 8 -2x +4
20x + 2x = 12 + 32
22x = 44
Dividing both sides by 22

Hence,
For x=2, the expression 4(5x-8) will be 4 more than the expression 2(4-x)
