Answer:

$4.50

Step-by-step explanation:

10% is the same as dividing something by 10. 45/10=4.5

The answer is 4.5

Think of the 10% as a fraction, \frac{10}{100}

\frac{10}{100} of 45 which just goes to \frac{10}{100} X 45 = 4.5

For me, if it's ever 10% of anything, you just move that imaginary decimal one place to the left and you get your 10 percent!!

The perimeter of a rectangle is 32cm, its length is more than its width by 2 what's the area​
White raven [17]

Answer:

63 cm^2

Step-by-step explanation:

p = l + w + l + w

32 = 2l + 2w

32 = 2(w + 2) + 2w

32 = 2w + 4 + 2w

32 = 4w + 4

28 = 4w

7 = w

l = w + 2

l = 7 + 2

l = 9

Check your work:

32 = 9 + 7 + 9 + 7

32 = 32

Correct

A = l × w

A = 9 × 7

A = 63

Basic factoring. Please help!
exis [7]

Answer:

3rd Option: -1(x + 15)

Step-by-step explanation:

When we factor our a negative 1, we take the opposite signs of what is given:

-1(x + 15)

To check, we simply just redistribute to check if it matches the original expression:

-x - 15

So the 3rd option is the correct choice.
