Please help solve

f(x) = 54x2 + 208x – 308
g(x) = -2x - 8

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

step-by-step explanation:

the answer is 128

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
