Answer:
A=80
Step-by-step explanation:
Area= length x width
L= 16
w= 5
Area= 16 x 5
Area= 80
Answer:
(The common base is 2).
Step-by-step explanation:
You have the equation given in the problem:

Then base of
is 2. Therefore, the common base must be 2.
If you add 3 to both sides of the equation, you obtain:


If you descompose 8 into its prime factors, you obtain that it can be written as:
8=2*2*2=2³
Therefore, you can you rewrite each side of the equation as following:

Where the common base is 2.
Answer: x = - 12/9 ( the equation is negative)
Step-by-step explanation:
\frac{5}{3}x+\frac{1}{3}=13+\frac{1}{3}x+\frac{8}{3}x
\frac{5}{3}x=3x+\frac{38}{3}
\frac{5}{3}x-3x=3x+\frac{38}{3}-3x
-\frac{4}{3}x=\frac{38}{3}
3\left(-\frac{4}{3}x\right)=\frac{38\cdot \:3}{3}
-4x=38
\frac{-4x}{-4}=\frac{38}{-4}
x=-\frac{19}{2}
