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:
The value of m is 1000 for r=5
Step-by-step explanation:
Given that m is proportional to the cube of r
It can be written as:

When the proportionality symbol is removed a proportionality constant is introduced in the equation.
Let k be the proportionality constant

Given
r=3,m=216
Putting the values

The equation will now become

Putting r = 5

Hence,
The value of m is 1000 for r=5
Answer:
4 * (x-9)=-30
not sure if u want it solved but if u do its x=6/4
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Given
14 + 10y ≥ 3( y + 14) ← distribute
14 + 10y ≥ 3y + 42 ( subtract 3y from both sides )
14 + 7y ≥ 42 ( subtract 14 from both sides )
7y ≥ 28 ( divide both sides by 7 )
y ≥ 4 → B
