Because y is 8 and x is 3 you just have to add it in the equation which means to times it,(8)2-3(3)
8x2=16
3x3=9
16-9=7

A swimming pool has a perimeter of 80 feet the short side measures 16 feet what is the length of the longer sides of the pool
svlad2 [7]

2 x (L + W) = Perimeter

2(L + 16) = 80   Then divide both sides by 2

L + 16 = 40         Then subtract 16 from both sides

L = 24 feet

4cos(10x)+2=2<br><br> What would this equal in Degrees??
Ipatiy [6.2K]

Answer:

Simplifying

4cos(10x) + 2 = 2

Remove parenthesis around (10x)

4cos * 10x + 2 = 2

Reorder the terms for easier multiplication:

4 * 10cos * x + 2 = 2

Multiply 4 * 10

40cos * x + 2 = 2

Multiply cos * x

40cosx + 2 = 2

Reorder the terms:

2 + 40cosx = 2

Add '-2' to each side of the equation.

2 + -2 + 40cosx = 2 + -2

Combine like terms: 2 + -2 = 0

0 + 40cosx = 2 + -2

40cosx = 2 + -2

Combine like terms: 2 + -2 = 0

40cosx = 0

Solving

40cosx = 0

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Divide each side by '40'.

cosx = 0.0

Simplifying

cosx = 0.0

The solution to this equation could not be determined.
