If the perimeter of a square is 4x - 24, what is the<br> area of the square?

DedPeter [7]

Answer:

A = (x - 6)² sq. units or

A = (x² - 12x + 36) sq. units

Step-by-step explanation:

P = 4s, where s is the side.

4s = 4x - 24

s = x - 6

A = s²

A = (x - 6)² sq. units or

A = (x² - 12x + 36) sq. units

Someone help pls :,)

Semenov [28]

Answer:

W = 87 degrees

Step-by-step explanation:

First we can rearrange the question so that W is isolated on the left side, which we do by dividing both sides by tan:

tanW/tan = 19.0811/tan

W = 19.0811/tan

Now we can use the inverse tan function on the calculator ( $tan^{-1}$ ) to calculate it:

W = 19.0811 x $tan^{-1}$

W = 87 degrees

Hope this helped!

Tia is planning a sailing party for her friends. The boat rental is $150 plus an

mars1129 [50]

Answer:

16 people

Step-by-step explanation:

First subtract the cost of the rental from the amount of money:

$400-$150 = $250

Therefore Tia has $250 to spend for additional people. Then if each person is $15, divide the remaining amount of money by the amount of money per person:

$250/$15 = 16.67

Since you can't have 0.67 of a person she can have 16 people go with her.

This can also be modeled by this inequality:

$150 + 15x \leqslant 400$
