Answer:
Step-by-step explanation:
1) Expand.
2) Simplify 7a + 5a + 15 to 12a + 15.
3) Simplify 8a + 4a + 8 to 12a + 8.
4) Cancle 12a from both sides.
5) Since 15 = 8 is false, there's no solution.
Therefor, this equation has no solution.
Pretty sure it’s figure 2
SA = 2bA (base area) + LA (lateral area)
bA = r^2*pi = 13^2pi = 169pi cm^2
LA = 2r*pi*h = 2*13*pi*88,4 = 2298,4pi cm^2
SA = (2*169pi)+2298,4 pi = 338pi+2298,4pi = 2636,4pi
Answer:
234 cm²
Step-by-step explanation:
Given expression to represent the surface area of the rectangular prism is
The given value of x is 3.
Now, finding value of expression by sustituting value of "x" as given.
Surface area of the rectangular prism =
Surface area of the rectangular prism=
∴ Surface area of the rectangular prism=
Surface area of the rectangular prism=
∴ Surface area of the rectangular prism= 234 cm²
