Common denominator i believe. i’m not sure. hope this helps
Answer:
Area = 30 in.
<h3>
Step-by-step explanation:</h3>
the formula for an area of a trapezoid is A = (a+b)/2 × h
a = base (or bottom)
b = 2nd base (or top)
h = height
set up your equation as A = (10 + 5)/2 × 4
A = 15/2 × 4
A = 7.5 × 4
A = 30
The area of the trapezoid is 30 in.
Answer:
are you sure those are all the options because it is -82
Step-by-step explanation:
Answer:
1/5
Step-by-step explanation:
Answer: x=0.25
Step-by-step explanation: 1−8x=−16x2
Simplify both sides of the equation.
−8x+1=−16x2
Subtract -16x^2 from both sides.
−8x+1−−16x2=−16x2−−16x2
16x2−8x+1=0
16x2+−8x+1=0
Use quadratic formula with a=16, b=-8, c=1.
x=
−b±√b2−4ac
2a
x=
−(−8)±√(−8)2−4(16)(1)
2(16)
x=
8±√0
32
x=0.25
