Answer:8 mph
Step-by-step explanation:
Area of a trapezoid is height times the average of the bases,
A= 1/2 h (a + b)
Here we have height h=12 and bases a=30, b=12 so area
A = (1/2) (12) (30 + 12) = 6(42)= 252
Answer: B
Answer:
35 degrees.
Step-by-step explanation:
It's a reflective sideway triangle.
Answer:
y=10
Step-by-step explanation:
(y-10)^2=0
Take the square root of each side
sqrt((y-10)^2)=sqrt(0)
y-10 =0
Add 10 to each side
y-10+10=0+10
y = 10
-3(x-5)-2x=-10
Distribute.
-3x+15-2x=-10
Combine like terms.
-5x+15=-10
Subtract 15 on both sides.
-5x=-25
Divide by -5 on both sides.
x=5
I hope this helps!
