Well, we should start by listing the factors

1,2,3,4,6,8,9,12,16,24,36,72

You can put these in pairs if it will help you,

1*72  2*36  3*24  4*16  6*12  8*9

If you look, you can see that in only one pair the length is twice the width.

So your answer is

W=6

L=12

A right triangle is displayed.
Mazyrski [523]

Answer:

You have to use the Pythagorean Theorem to find the other side, which will be your base in the Area formula (A=1/2bh). So the Pythagorean theorem would be 36^2 + b^2 = 60^2. This gives you 48 in for your base/missing side length. Then, you plug it into the area formula. So, A=1/2(48) (36). This gives you 864 in^2 for the area of your triangle.

If f(x) = 3^2 + 10x and g(x) = 2x-4, find (f-g)(x).
Marat540 [252]

What we know:      

f(x)=3^2+10x\\g(x)=2x-4                

(Also, 3^2=9)

What we need to solve:

(f-g)(x)             (This is equal to f(x)-g(x))

How you have to subtract f(x) with g(x) to get:

(f-g)(x) = f(x)-g(x) = 9+10x+2x-4 = 12x+5

Thus, the answer would be:

12x+5

27millimeters. 1cm/10mm
Alla [95]
If you would like to know how many centimeters are 27 millimeters, you can calculate this using the following steps:

1 cm ... 10 mm
x cm = ? ... 27 mm

1 * 27 = 10 * x
27 = 10 * x    /10
x = 27/10
x = 2.7 cm

The correct result would be 2.7 cm.
