Answer:
B: 13.5 in^2
Step-by-step explanation:
The average length of this trapezoid is (4 in + 5 in)/2, or 4.5 in.
The height is 3 in.
Thus, the area is A = (average length)(height) = (4.5 in)(3 in) = 13.5 in^2

Answer: x+4</h3>
This is because the given expression factors to (x+4)(x+4), which condenses to (x+4)^2.
To factor, think of two numbers that A) multiply to 16, and B) add to 8. Those values would be 4 and 4
4+4 = 8
4*4 = 16
So that's how we end up with (x+4)(x+4). You can use the FOIL rule to expand that out and get x^2+8x+16 again to help verify you have the correct factorization.

Answer:
3/4 divided by 1/6
3/4 multiplied by 6/1
18/4 = 4 2/4 and simplify to 4 1/2
4 1/2 minutes.
Step-by-step explanation:
Answer:
m = -3 , b = 5
Step-by-step explanation:
y = -3x+5 (equation 1)
y = mx+b (equation 2)
equation 1 = equation 2
; m = -3
b = 5
