Linda is adding padding to all of the surfaces inside her attic for extra warmth in the winter. She needs to find the approximate surface area of the attic, including the walls, floor, and
ceiling. The attic is in the shape of a triangular prism. Linda draws the net and writes
the expression below to represent the surface area of the attic. Are Linda's net and
expression correct?
- 15 ft
45 ft
25 ft
40 ft
25 ft
25 ft
25 ft
- 15 ft
45 ft
40 ft
15 ft
Expression for Surface Area of Attic:
45 (40 + 25 + 25) + (40 x 15)

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

=240

=48
