Answer:
A. 8
Step-by-step explanation:
sqrt{64} is 8 (8*8)
A = LW + 0.5bh
0.5bh = A - LW
b = (A - LW) / 0.5h
Its B
Note to avoid ambiguity its better to put the A - LW in parentheses
Answer:
a = - 4, b = 5
Step-by-step explanation:
Expand the left side, then compare the coefficients of like terms.
- 3(2x² + ax + b)
= - 6x² - 3ax - 3b, compare to - 6x² + 12x - 15
Compare coefficients of x- terms
- 3a = 12 ( divide both sides by - 3 )
a = - 4
Compare constant terms
- 3b = - 15 ( divide both sides by - 3 )
b = 5
