Hello!

\large\boxed{-16}

Use PEMDAS (order of operations) to solve:

-4 · [3 + (-5)²] ÷ 7

Square -5:

-4 · [3 + 25] ÷ 7

Add the numbers inside of the parenthesis:

-4 · [28] ÷ 7

Multiply -4 and 28:

-112 ÷ 7

Divide:

= -16.

You've been working with rectangular prisms all night, and the same formula gives the volume of every one of them.  Unfortunately, you used way more time asking other people for answers than it would take you to solve them on your own.

The formula is:

             Volume  =  (length)  times  (width)  times  (height) .

With that formula, you can directly solve problems #1, #2, #3,
#4, and #8.  It's also the only math you really need to solve #9 ...
but you also need to use your brain cells for #9.


For #6, start with the same formula:

                                     Volume = (length) x (width) x (height)

Divide each side by
(width) x (height), and
then it says:               Length = (volume) / (width x height) .

#6 gives you the volume, width and height. 
 You can just write them into this equation,
and bada-bing, you'll have the missing length.

In 10 years, a child’s age will be 6 years less than triple her current age. Find the child’s current age.
Pavel [41]

Answer:

Her current age is 8 years old.

Step-by-step explanation:

Current age: x

"In 10 years, a child’s age will be 6 years less than triple her current age."

In 10 years: <u>x + 10</u>

6 years less than triple: <em>3x - 6</em>

<u>x + 10</u> = <em>3x - 6</em>

<em>solve.</em>

<em>16 = 2x</em>

<em>x = 8</em>
