Answer:

33 - 2x =  {x }^{2}  + 2x + 1 \\  {x}^{2}  + 4x - 32 = 0 \\ x = 8 \\   \\ x = 4

Answer:

x = 4

Step-by-step explanation:

(33-2x)^(1/2) = x + 1

33-2x = x^2 + 2x + 1           [square both sides]

x^2 + 2x + 1 - 33 +2x = 0

x^2 + 4x - 32 = 0

(x - 4)(x + 8) = 0

x = 4

Louis built a swimming pool. The depth of the swimming pool is 5 feet. What is the volume of water that it will take to fill the
julia-pushkina [17]

Answer:

For a rectangular prism-like swimming pool: V = w\cdot l \cdot h. V = 360\,ft^{3} when h = 5\,ft, l = 12\,ft and w = 6\,ft.

Step-by-step explanation:

Let assume that swimming pool has a rectangular base and depth is the same  at any point at the bottom. In addition, let w and l be the width and length of the swimming pool. Then, the volume needed to fill the swimming pool is:

V = w\cdot l \cdot h, where h is the depth of the pool.

Let be h = 5\,ft, l = 12\,ft and w = 6\,ft. The volume of the swimming pool is:

V = (6\,ft)\cdot (12\,ft)\cdot (5\,ft)

V = 360\,ft^{3}

I am struggling with triangles missing angles with the formula if you could explain your answer step by step that would be great
Alborosie

Answer:

See below.

Step-by-step explanation:

The 3 angles of all triangles add up to 180 degrees.

An isosceles triangle has 2 of its angles equal.

So if one of the angles is 130 degrees then there cant be another one of 130 degrees as that would make 260 degrees.

So the other 2 angles are equal and their measure is (180 - 130) / 2

= 50 / 2

= 25 degrees.

The 2 equal angles are both 25 degrees.
