The answer is D
3*-42=-126
The factors of -126 that add to -11 are 7 and -18
replace -11h with 7h-18h
3h^2 + 7h - 18h - 42
Factor the first two terms and last two terms
h(3h+7) - 6(3h+7)
See how the two parentheses are the same?
THE ANSWER IS BELOW!!
(h-6)(3h+7)
the first parentheses has the terms that were outside, and the second has the original bracketed terms
This matches option D (it just multiplies the terms backwards, which gives the same result)

Answer:
we have
when
base=8cm
height=11cm
area of parallelogram is :base×height
=8*11=88cm³
Now for
base=15cm
height=h
we have
the area of parallelogram=88cm²
base ×height=88cm²
15*h=88
h=88/15
h=88/15 or 5 13/15 or 5.86 cm in approximately
