Let the width be w, then the length is 2w - 2.5.
Perimeter = 2(length + width)
40.6 = 2(2w - 2.5 + w) = 2(3w - 2.5)
3w - 2.5 = 40.6/2 = 20.3
3w = 20.3 + 2.5 = 22.8
w = 22.8/3 = 7.6
Therefore, width is 7.6 cm.
<h2><u>Polynomial Function</u></h2>
<h3>Evaluate the following function: Show all work! h(x)=3x²+2-2x, Find h(-2)</h3>
To determine the answer, substitute the given value to the function and simplify.
- h(x) = 3x² + 2 - 2x; h(-2)
- h(-2) = 3(-2)² + 2 - 2(-2)
- h(-2) = 3(4) + 2 + 4
- h(-2) = 12 + 2 + 4
- h(-2) = 14 + 4
- h(-2) = 18

Answer:
7^2
3^3
Step-by-step explanation:
Exponents signify how many times the base is multiples by itself. In the case of 7x7, 7 is the base and it is being multiplied by twice itself, resulting in an answer of 7^2
Step-by-step explanation:
The Mathematical expression would be given as:
- (70 + 2n)
Where n represents any given year.
Negative sign is taken as it symbolises depth below sea level.
