Answer:

C on Edge2020: Cubing both sides once.

Step-by-step explanation:

In order to get rid of the radicals in the equation, we must cube both sides.

\sqrt[3]{5x-2} -\sqrt[3]{4x} =0 is the original equation. Cube both sides:

5x-2-4x=0 is what we have now that we have gotten rid of radicals.

Simplify by combining like terms and solve for x.

x-2=0

x=2

Note that we have cubed both sides only once. Therefore, C is the solution.

Semenov [28]

Answer:

7 1/2 quart of paint

Step-by-step explanation:

To get the correct color, Johan mixed 3 1/4 quart of white paint, 1 2/4 quart of blue paint, and 2 3/4 quart of green paint. How much paint did Johan make? *

The above question is solved as:

3 1/4 quart + 1 2/4 quart + 2 3/4 quart

Lowest common denominator = 4

3 + 1 + 2 + ( 1/4 + 2/4 + 3/4)

= 6 + ( 1 + 2 + 3/4)

=( 6 + 6/4) quart

= 6 + 1 2/4 quart

= 7 2/4 quart of paint

= 7 1/2 quart of paint

Therefore, Johan made 7 1/2 quart of paint

The total number of degrees, D, in an n-sided polygon is given by the formula D=180(n-2). When Janelle solves for n, she gets n=
Rus_ich [418]
<span>D = 180 * (n -2)
D = 180n -360
180n = D +360
n = (D / 180) + 2

So, the answer is "A"
And we can test this with a square, sum of angles = 360
n = (D / 180) +2
n = (360 / 180) +2
number of sides = 4
correct
