Answer:
A. 862.4 in^2
Step-by-step explanation:
1) (14x8.9)=124.6
124.6x4(4 sides have the same surface area)=498.4
2) 13x7(half of the 14in)=91
3) Typically, to find the surface area of a right triangle, you would divide the answer by 2, but since we have 8 right triangles, we can just multiply the 91 by 4. 91x4=364
4) 364+498.4=862.4 in^2
Step-by-step explanation:

Answer:
The answer is c, 783.67
Step-by-step explanation:
you add 850+832+669=2351
because it is for 3 months, you divide it by 3. 2351/3=783.6666666667
They say round to nearest cent, which is 783.67
The dimensions of the prism can be 2x, 2x+3 and x+6.
We first factor out the GCF of the trinomial. The GCF of the coefficients is 2. Each term has an x in common as well, so the GCF is 2x.
Factoring out the 2x, we have
2x(2x²+15x+18).
To factor the remaining trinomial, we find factors of 2*18=36 that sum to 15. 12*3 = 36 and 12+3 = 15. We split up 15x into 12x and 3x:
2x(2x²+12x+3x+18)
Now we group together the first two terms in parentheses and the last two:
2x((2x²+12x)+(3x+18))
Factor out the GCF of the first group:
2x(2x(x+6)+(3x+18))
Factor out the GCF of the second group:
2x(2x(x+6)+3(x+6))
Factoring out what these have in common,
2x(x+6)(2x+3)
