Answer:
2A/ (b1-b2) =h
Step-by-step explanation:
A = 1/2 (b1-b2) *h
Multiply each side by 2
2A = 2 *1/2*(b1-b2) *h
2A = (b1-b2) *h
Divide by (b1-b2)
2A/ (b1-b2) = (b1-b2)/(b1-b2) *h
2A/ (b1-b2) =h

Answer:
4x² - 28xy + 49y²
Step-by-step explanation:
(2x - 7y)²
= (2x - 7yy)(2x - 7y)
Each term in the second factor is multiplied by each term in the first factor, that is
2x(2x - 7y) - 7y(2x - 7y) ← distribute parenthesis
= 4x² - 14xy - 14xy + 49y² ← collect like terms
= 4x² - 28xy + 49y²
