Answer:
2x(x+y)(x-y)
Step-by-step explanation:
Given the expression;
(x+y)² + 2(x+ y)(x- y) + (x– y)²
Factorize
(x+y)² + (x+ y)(x- y) + (x+ y)(x- y) + (x– y)²
= (x+y)[x+y+(x-y)] +(x-y)[(x+y)+(x-y)]
= (x+y)(x-y)(x+y+(x-y))
= (x+y)(x-y)(x+y+x-y)
= (x+y)(x-y)(2x)
hence the expanded form is 2x(x+y)(x-y)

Answer:
$7.09
Step-by-step explanation:
$0.59(5) = $2.95
$2.49(4) = $9.96
$9.96 + $2.95 = $12.91
Subtract $12.91 from the original amount Johnny had.
$20 - $12.91 = $7.09
