Easy bruh

Answer:

6w^3

Step-by-step explanation:

It can't be any answer with cubed in it because that would be volume. So, A and C magically vanish. If we know that the length of a cube is w that means that all sides are w. There are six faces on a cube. If we want to find surface area we will have to add up the area of all faces. the area of one face will be w^2. We multiply that number by six and we get 6w^3.

The answer is <em>letter b. </em>This is because b is the proper expression that represents the surface area of a cube.

A scientist has two solution which she labelled, solution A and solution B, each continue salt,she knows that solution A is 65%

Lorico [155]

A = oz of the solution A

b = oz of the solution B

The scientist knows that solution A is 45% salt and solution B is 95% salt. She wants to obtain 80 ounces of a mixture that is 65% salt.

a + b = 80

0.45a + 0.95b = 0.65*80

by solving the above system of equations you'll find····

a = 48 oz

b = 32 oz

~I hope this helped~

If it doesn't make since, I can try to switch up the wording ^^

Can u help sold this

solong [7]

Answer:

Step-by-step explanation:

To calculate the slope or gradient we use this formula:

Slope = y2-y1/x2-x1

(-3,2) = (x1, y1)

(4,2) = (x2, y2)

Slope = 2-2/4-(-3) = 0

Wich number is the principal square root of 49

myrzilka [38]

A principle square root of a real number that's not negative, such as 49, is the square root of that number that is not negative.

If you take the square root of 49, you get either -7 or 7, since both $7^{2}$ and $(-7)^{2}$ equal 49. However, the principle square root would be A) 7, since it's not negative.
