Answer:
D.
Step-by-step explanation:
h(x)=f(x)g(x) means multiply the expression for f to the expression for g.
That is the problem is just asking you to do (11x-5)(-2x-4).
Let's use foil.
First: 11x(-2x)=-22x^2
Outer: 11x(-4)=-44x
Inner: -5(-2x)=10x
Last: -5(-4)=20
------------------------Add together!
-22x^2-34x+20
D.
To find the new sides take the original sides and multiply it by the scale factor
12 * 1.5 = 18
10 * 1.5 = 15
14 * 1.5 = 21
So the new sides are 18, 15, 21. And they correspond to the 12, 10, and 14 respectively
Answer:
Step-by-step explanation:
we know that
The perimeter of a rectangle is equal to
----> equation A
where
L is the length
W is the width
we have
The length is 3 inches more than twice the width
so
----> equation B
substitute equation B in equation A
Combine like terms
36 inches is equal to 3 feet. He would multiply the length of each curtains (3ft) by the amount of curtains he needs(71) he would need 213 feet of fabric
