Okay, so first things first:
i =

That said, no answer that has -245 is correct.
Now we just need to solve

245/5=5*49

So, that's your answer, option D.
Area of a circle is pi x r^2
R = d/2 = 14.2 = 7
Area = 3.14 x 7^2
Area = 3.14 x 49
Area = 153.86 round to 154
Answer is 154 square feet.
Answer:
Step-by-step explanation:
For this case we have the following polynomial:

We make the following change of variables:

Rewriting we have

Factoring the second order polynomial we have:

Then, returning the change we have:

Finally, we factor the expression in the parentheses of the second term:

Answer:
the completely factored form is:

Answer:
326m²
Step-by-step explanation:
Find the area of each side and find the total sum from each individual area:
2(15*4)+2(7*4)+2(7*15)=2(60)+2(28)+2(105)=2(163)=326
So the surface area of the prism is 326m²
