To find the area of a polygon use the formula Area = 1/2 x perimeter x apothem
Answer:
-27x^5y^-1 z
Step-by-step explanation:
<u>81x⁷yz³</u>
-3x²y²z²
-27x^5y^-1 z
For this case we must solve the following equation:

For this, we follow the steps below:
We find the Neperian logarithm on both sides of the equation to remove the variable from the exponent

We use one of the logarithm properties to extract x from the exponent:

We subtract xln (7) on both sides of the equation:

We take x common factor:

We divide between
on both sides of the equation, then:

Answer:

Answer:
$40
Step-by-step explanation:
100% - 20% = 80%
80% of $50 = 0.8 × $50 = $40
