Answer:
188 feet squared
Step-by-step explanation:
The formula for a trapezoid is A = [(a+b)/2]h
1. Find base a and b: 28ft and 19ft
2. Find the height: 8ft
3. Plugin: A = [(28+19)/2]8
4. Solve:
A = (47/2)8
A = 23.5 x 8
A = 188 feet squared
Answer:
-2 or -5
Step-by-step explanation:
(2x − 8) / (x² + 7x + 10) is an invalid expression when the denominator is 0.
x² + 7x + 10 = 0
(x + 2) (x + 5) = 0
x = -2 or -5
Answer:
The x is for you to multiply <30
angle for triangle is 180°
angle ACB is 75° because it has mention that is an isosceles triangle
So that angle of BAC is 180°-75°-75°=30°
Formula for circumference= (2)(pi)(r) or (pi)(d)
diameter=2r=6ft
6ft*3.14=18.84
