Answer: 19
Reasoning: the equation is 7 + (6 x 2) = 19
Let
x---------> the length of the sides that have the same length in meters
we know that
the perimeter of the figure is equal to

<u>solve for x</u>



therefore
<u>the answer is</u>
Each of the same length side is
long
Answer:
a) 81
b) 16,807
c) 100
d) 78125
Step-by-step explanation:
a)
3^2 x 3^2

c)
10^9 divided by 10^7
Step 1. Simplify the exponents
10^9 = 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 x 10 = 1000000000
10^7 = 10 x 10 x 10 x 10 x 10 x 10 x 10 = 10000000
Step 2. Divide
1000000000 divided by 10000000 = 100
