Answer:
x=13
Step-by-step explanation:
Divide both sides by three to get rid of the three this makes x=13
Answer:
105
Step-by-step explanation:
180 - 140 = 40
180 - 145 = 35
35+ 40 = 75
180 - 75 = 105
a = 5
Hi there!

We can begin by finding the area of the base in order to solve for the volume.
Use the formula for the area of a trapezoid:
A = 1/2(b1 + b2)h
Substitute the given values:
A = 1/2(10 + 6)5
A = 1/2(16)5
A = 40 cm²
Multiply by the depth of the prism to solve for the volume:
40 × 8 = 320 cm³
So 53.5 + 12.9 =66.4 then thats a. -66.4
