A room has an area of 216 square feet. One dimension is 6 feet more than the other. Find the length of the longer side.
zlopas [31]
The dimensions would be x and x+6. The area is 216.

x(x+6) = 216
x^2 + 6x - 216 = 0
(x-12)(x+18) = 0

x = 12---Yes---
x = -18---No, sides cannot be negative---

If one side is 12, the other side is 18. To check:

12 * 18 = 216
216 = 216

Correct

Whoever gets it right can have brainliest, but answer ASAP!
Scilla [17]

Answer:

Hi!~I~am~beinggreat78,~and~I~will~help~you!

Let's start by breaking down the problem.

This is how it should look. ↓

60 ÷ 20 ⇒ + 3 ⇒ x * 5^2

What does that <em>x</em> mean? <em>x</em> is just a substituted value for the first 2 equations.

Now, we can solve.

60 ÷ 20 = 3

Add 3

3 + 3 = 6

Now, multiply 6 times 5 squared. What does 5 squared mean? 5 squared is just 5 times itself once. You most likely want to solve 5 squared before multiplying.

5^2~or~5 * 5 = 25

And now for the last step, multiply 25 times 6

25 * 6 = 150

With that information, the problem is solved! Your answer is 150

The Quotient 250 divided by 5/8 tells about how far a sloth may move in one hour How far can a sloth go in 90 minutes?
Hunter-Best [27]

Given condition is:

A sloth moves in one hour = \frac{250}{5/8}

\frac{5}{8}=0.625

So, a sloth moves in one hour = \frac{250}{0.625}=400 units

Hence, in 60 minutes a sloth moves = 400

In 1 minute sloth will move = \frac{400}{60}

In 90 minutes it will  move = \frac{400}{60}\times90=600

The answer is 600 units.
