Solve for V over the real numbers:

V^2 = 12^2 - 6 2 9

12^2 + 2 (-6) 9 = 36:

V^2 = 36

Take the square root of both sides:

Which two expressions will find the total volume of the figure below?
IRINA_888 [86]
The volume of the prism:
V = L x W x H,
where L is the length, W the width and H the height.
We can find the volume of the entire figure by adding together the volumes of two smaller figures ( 2 prisms ).
The 1st one has dimensions: 2, 2, 7 and the 2nd has dimensions 2, 3, 8.
Answer:
B . ( 2 x 2 x 7 ) + ( 2 x 3 x 8 )

Using the keys above, enter an expression equivalent to (-7x^2+4x-3)+(6x-15) using the fewest possible terms.
navik [9.2K]

Answer:

Final answer in simplified form is -7x^2+10x-18

Step-by-step explanation:

Given expression is (-7x^2+4x-3)+(6x-15)

Now we need to find an equivalent expression for (-7x^2+4x-3)+(6x-15)

First we can distribute the positive sign and remove the parenthesis the combine like terms

(-7x^2+4x-3)+(6x-15)

=-7x^2+4x-3+6x-15

=-7x^2+4x+6x-3-15

=-7x^2+10x-18

Hence final answer in simplified form is -7x^2+10x-18

What is the justification for step 4 in the solution process?
iogann1982 [59]

Answer:

Multiplication property of equality

Step-by-step explanation:

Given

Step 4: b = -27/8

Required

Which property justifies it?

First, it should be noted that step 4 is a result of step 3

When step 3 is multiplied by 3/8 on both sides, we have step 4;

i.e.

\frac{8}{3b} = -9

\frac{8}{3b} * \frac{3}{8} = -9 * \frac{3}{8}

b = -9 * \frac{3}{8}

b = \frac{-9 * 3}{8}

b = \frac{-27}{8}

<em>The property that allows 3/8 be multiplied on both sides is referred to as the multiplication property of equality</em>
