What is the volume of the cube?
DENIUS [597]

Answer:

d) 343 cm^3

Step-by-step explanation:

Because you are talking about volume of a cube, that means all sides are equal. The equation for volume is length x width x height. Since all sides of the cube are equal and you are given the height, 7 cm, you will need to multiply 7 three times. Your equation would be 7 x 7 x 7. Then, 7 x 7 is 49 and 49 x 7 is 343. Don't forget, because we are talking volume, to put the cubed. So, your answer is 343 cm^3.

MariettaO [177]

Answer:

B

Step-by-step explanation:

40+88+15=128+15=143

There are three rectangles that compose this shape. The first one has side lengths of 5 & 8 (l times w=a 5 times 8=40, area of the rectangle is 40). The second one has side lengths of 8&11 (8 times 11=88, area is 88). Final rectangles has side lengths of 16-(8+5) and 5 (16-13=3, 3 times 5=15, Area=15). All three of those rectangles added up is 143 as an area of the figure.

I nee d help with this because my teacher didn't explain it well.
koban [17]

To solve 10x-35+3ax=5ax-7a, we'll need to assume that a is a constant and that we are to solve for the variable x.  To accomplish this, group all the x terms together on one side and all of the no-x terms on the other:

10x + 3ax - 5ax = -7a + 35

Factoring x out of the left side, we get:

x(10 - 2a) = 7(5 - a).  Dividing both sides by (10 - 2a), we get:

       7(5 - a)

x = ------------ = 7/2

      2(5 - a)

x has the value 7/2.
