Answer:
The answer is 2.4
Step-by-step explanation:
5x + 10 + 58 = 180
5x + 68 = 180 Subtract 68 on both sides
5x = 112 Divide 5 on both sides to get "x" by itself
x = 22.4
3.60 is the answer for your question
Answer:
128 + 96√3 or 294.28 unit^3 to the nearest hundredth.
Step-by-step explanation:
The surface area of one of the pyramids = area of the square base + area of the 4 equilateral triangles
= 8^2 + 4 * 1/2 * 8 * 4√3
= 64 + 64√3.
So the area of the new solid = 2(64 + 64√3) - area of 2 triangles
= 2(64 + 64√3) - 32√3
= 128 + 128√3 - 32√3
= 128 + 96√3.
X= the total amount
X- 120+ 50+ 400= What Jessica owes
