Use the FOIL method to find the trinomial.
FOIL - First, Outer, Inner, Last
(Bolded terms are the terms being multiplied.)
First
(
4x + 5)(
9x + 9)
Outer
(
4x + 5)(9x +
9)
Inner
(4x
+
5)(
9x + 9)
Last
(4x
+
5)(9x +
9)
Add all of these results together:
Simplify by combining like terms.

17.)
Answer:
144m
Step-by-step explanation:
we would used tan 30 to determine the height of the building
tan 30 = opposite / adjacent
0.5774 x 250 = 144m
Answer:
x=6
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
1/10(x+34)=−2(4−x)
(1/10)(x)+(1/10)(34)=(−2)(4)+(−2)(−x)(Distribute)
1/10x+17/5=−8+2x
1/10x+17/5=2x−8
Subtract 2x from both sides.
1/10x+17/5−2x=2x−8−2x
−19/10x+17/5=−8
Subtract 17/5 from both sides.
−19/10x+17/5−17/5=−8−17/5
−1910x=−57/5
Multiply both sides by 10/(-19).
10/−19)*(−19/10x)=(10/−19)*(−57/5)
x=6
Answer:
Well, any number that is not 5 for the y-intercept
Step-by-step explanation:
As you could tell not matter how I change the y-intercept it is always parallel to the line y=2x + 5
