Answer:
2x^2 - 2
Step-by-step explanation:
FOIL:
First outer inner last.
So we take (x-1) and (2x+2) and multiply the two first terms together.
2x^2
Next, we do the two outer terms.
2x^2 + 2x
Inner is next.
2x^2 + 2x - 2x
Then the last two terms in the equation.
2x^2 + 2x - 2x - 2
Then simplify:
2x^2 - 2
Answer:
$420
Step-by-step explanation:
Divide to isolate the cost
240 / 4 = 60 - amount per person (for 4 people)
60 / 5 = <u>12</u> - amount per person per day (5 days)
Multiply using that cost and new values.
12 x 5 = 60
60 x 7 = 420
Answer:
$270
Step-by-step explanation:
F(x)= x²+5x
f(x)= -2²+5(-2)
f(x)= 4-10
f(x)= -6

A:
Width of the deck = 
units
Length of the deck = 
units
So area of rectangular deck = Length * width
= 
Area = 
Area= 
units square
As mentioned in part B, the area of the pool is 
so the combined area of the deck and pool is
Area = area of rectangular deck + area of pool
= 
unit square
B:
The area of only the deck is unit square
