What is the volume of the prism shaped containers
ss7ja [257]

Answer:Volume of a cube = side times side times side. Since each side of a square is the same, it can simply be the length of one side cubed. If a square has one side of 4 inches, the volume would be 4 inches times 4 inches times 4 inches, or 64 cubic inches. (Cubic inches can also be written in3.)

Can someone please help me with this question please ?
EleoNora [17]

Answer:

x=43

Step-by-step explanation:

Since the lines are parrallel, the angle underneath the one you are finding is equal to 65. To find the total value of (x+72) you subtract 65 from 180, giving you 115.

x+72 = 115

then you subtract 72 from both sides

x=43

The expression 7+3x+4 represents the perimeter of the triangle. Simplify the expression.
anyanavicka [17]

Answer:

-3.6

Step-by-step explanation:

Simplifying

7 + 3x + 4 = 0

Reorder the terms:

7 + 4 + 3x = 0

Combine like terms: 7 + 4 = 11

11 + 3x = 0

Solving

11 + 3x = 0

Solving for variable 'x'.

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

Add '-11' to each side of the equation.

11 + -11 + 3x = 0 + -11

Combine like terms: 11 + -11 = 0

0 + 3x = 0 + -11

3x = 0 + -11

Combine like terms: 0 + -11 = -11

3x = -11

Divide each side by '3'.

x = -3.666666667

Simplifying

x = -3.666666667
