Let's look at the formula to solve the perimeter.
2l+2w=98
We know that l=6w
Let's put that into the equation.
2(6w)+2w=98
12w+2w=98
14w=98
98÷14=7
So the width is 7. Let's find the length.
Since the length is six times the width: 7×6= 42
So, the length is 42 while the width is 7. We need to find the area.
42×7=294
The area is 294 m².

What numbers are 1.4 units from −3.2 on a number line? pick one from both sets of answers
Fantom [35]

First, add 1.4 to the number given.

-3.2 + 1.4 = 1.4 - 3.2 = -2.2

a.-2.2 is one of your answer

Next, subtract 1.4 to the number given

-3.2 - 1.4 = -4.6

a.-4.6 is your next answer

a. -2.2, a. -4.6 are your two answers

hope this helps

How do I get to the answer?<br><br> (3 x n) + 4 = 32/2<br><br> What is the value of n?
charle [14.2K]
If you simplify what's in the bracket, you get 3n

=(3n)+4=32/2
=3n+4= 32/2(here we can either crossmultiply or equate)
3n+4-4=32/2-4(subtract 4 from both sides)
3n=32/2-4
3n=24/2
3n=12
3n=12(divide both sides by the coefficient of the unknown)
3n/3=12/3
n=4

What is the value of m in the figure below? If necessary,round your answer to the nearest tenth of a unit
bogdanovich [222]

Answer:

D

Step-by-step explanation:

It turns out from similar triangles, that 7/BD = BD / 18. Use triangles  ABD and BDC to show this relationship. Solving this equation will give you BD

BD^2 = 7*18

BD^2 = 126     Just leave it in this form. Do your rounding at the end.

Because triangle BDC is a right angle triangle, use the Pythagorean Theorem to solve for m

m^2 =  BD^2 + 7^2

m^2 = 126 + 49

m^2 = 175                         Take the square root of both sides.

sqrt(m^2) = sqrt(175)

m = 13.22

so the answer is D

Semenov [28]
The only thing you should do is to divide 3,072 by 96 and the answer is 32.
So each of them should read 32 books :)))
