Answer:
<h2>652 ft²</h2>Step-by-step explanation:
Look at the picture.
It's a net of right rectangular prism.
We have three pairs of rectangles:
7ft × 8ft
7ft × 18ft
8ft × 18ft
The formula of an area of a rectangle l × w:
A = lw
Calculate the areas:
A₁ = (7)(8) = 56 ft²
A₂ = (7)(18) = 126 ft²
A₃ = (8)(18) = 144 ft²
The Surface Area :
S.A. = 2A₁ + 2A₂ + 2A₃
Substitute:
S.A. = 2(56) + 2(126) + 2(144) = 652 ft²
Answer:
Step-by-step explanation:
When we divide polynomials by polynomials with more than one term, we use long division or factorization to simplify.
This polynomial isn't easily divided after factorization so we will use long division. And we will use the remainder theorem to write any remainder.
We start long division by finding what multiplies with x+5 to get . This is 6x.
So . We have 6x left as a remainder from 36x.
We now divide x+5 into 6x+35. What multiplies with x+5 to get 6x+35? 6.
So we have 6x+6 as our answer so far and after we multiply 6(x+5)=6x+30 we will have a final remainder of 5.
We write our answer as .
