Answer:
8x+16 ft^2
Step-by-step explanation:
First we find the total area of the large rectangle
A = l*w
A = (x+3) * (x+5)
FOIL
A = x^2 +5x+3x+15
A = x^2 +8x+15
Now we find the area of the inner rectangle
A = lw
A = (x+1) (x-1)
FOIL
A = x^2 -x+x -1
A = x^2 -1
To find the shaded area, take the large rectangle and subtract the small rectangle
x^2 +8x+15 - (x^2 -1)
Distribute the minus sign
x^2 +8x+15 - x^2 +1
Combine like terms
8x+16

Answer:
34 m squared
A=bh/2
Step-by-step explanation:
10+24+24+10
10+10=20
24+24=48
48+20
=68/2
=34
Answer:
Step-by-step explanation:
(4-5i)(3-6i) = 4*(3-6i) - 5i(3 - 6i)
= 4*3 - 4*6i - 5i*3 + 5i*6i
= 12 - 24i - 15i + 30i²
= 12 - 39i + 30 * (-1) {i² = -1}
= 12 -30 - 39i
= -18 - 39i
Answer:hopes this will helpp
Step-by-step explanation:In the same way, I will combine these two like terms by adding the numerical portion of each term, while carrying the x along for the ride: 3x + 4x. (3 + 4) x. (7) x.
