How do you simplify this expression?

The expression -12 + 3*(-8 + (-4)² - 6) + 2 is equal to -4.

<h3>How to simplify the expression?</h3>

Here we have the expression:

-12 + 3*(-8 + (-4)² - 6) + 2

To simplify this, we need ti start by simplifying the parenthesis.

The first one is:

(-4)² = (-4)*(-4) = 16

Replacing that in the original equation we get:

-12 + 3*(-8 + 16 - 6) + 2

Now we need to simplify the other parenthesis:

-8 + 16 - 6 = -14 + 16 = 2

Replacing that we get:

-12 + 3*(2) + 2

Now we need to solve the products and divisions, so we need to solve the product in the second term:

3*2 = 6

Replacing that we get:

-12 + 6 + 2

Now we just solve that addition to get:

-12 + 6 +  2 = -12 + 8 = -4

We conclude that the expression -12 + 3*(-8 + (-4)² - 6) + 2 is equal to -4.

Lyrx [107]

Answer:

28.8 and 180

Step-by-step explanation:

you just times B by 2/5 to get C and divide it by 2/5 to get A

C = (72)(2/5) = 28.8 km³

A = (72)/(2/5) = 180 km³

We know the answers make sense because A shrinks to get B and B shrinks to get C, and our answers match that.

A child's sandbox is 5 feet wide, 4 feet long, and 3 feet deep. Grace fills the sandbox so that the sand is 2 ½ feet deep. What
8_murik_8 [283]

Answer:

the volume of sand is 50 ft^{3}

Step-by-step explanation:

This problem bothers on the mensuration of solid shapes, rectangular prism.

Given data

Length  l= 4 ft Width w= 5ft\\Height h = 3ft

if the sandbox is filled with sand of 2\frac{1}{2 } ft deep the volume of the sand in the box will be calculated based on the the depth of the sand

converting the depth of sand from mixed fraction to proper fraction we have 2\frac{1}{2} = \frac{5}{2}

the expression for the volume of a rectangular prism is

volume of sand = length * width* height

substituting our data into the expression we have

volume of sand= 5*4 * \frac{5}{2} \\volume of sand = \frac{100}{2} \\volume of sand = 50 ft^{3}
