What is the area of the figure?

answer is c = 390

Step-by-step explanation:

first find the area of rectangle

15 times 20 = 300

next find area of triangle

15 times 12 divided by 2 = 90

add the two areas together

300+90=390

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
