h(x) = 4x² - 5x

h(-3) is x = -3

<u>Step 2: Evaluate</u>

  1. Substitute:                    h(-3) = 4(-3)² - 5(-3)
  2. Exponents:                   h(-3) = 4(9) -  5(-3)
  3. Multiply:                        h(-3) = 36 + 15

A rectangular field has an area of 162 m² the width of this field is 9m what is the perimeter of this field
Andru [333]

Answer:

54 m

Step-by-step explanation:

Alrighty, what have we here: an area of 162 m² and a width of 9m.

So: A=162m², W=9m, let's draw this: (see the screenshot attached)

Using the formula for area (Area = width x length) we see that:

162m^{2} =9m*L

Thus: (equating to L by dividing both sides by 9m)

⇒ \frac{162m^{2} }{9m}=18m=L

Now we have all of our dimensions, we can use the formula for the perimeter to calculate it:

perimeter=2W+2L=2*9m+2*18m=18m+36m=54m

And there we have our answer.
