Step-by-step explanation:
<u>The distance is the difference in top and bottom positions:</u>
- 4 - (-9) = 4 + 9 = 13 inches
Step-by-step explanation:
area of ∆ = .5*b*h
b= x+5
h= x-5/2
let's do (x+5) * (x-5/2)
x^2+5x-5/2x-25/2
x^2+5/2x-25/2
area = .5x^2+5/4x-25/4
Answer:
x=12
Step-by-step explanation:
11x - 17 + 65 = 180
11x + 48 = 180
<u> -48 -48 </u>
<u>11x </u>= <u>132</u>
11 11
x = 12
Answer:Since the expression on each side of the equation has the same denominator, the numerators must be equal.
