PERIMETER = 2 (LENGTH + WIDTH)
PERIMETER = 2 LENGTH + 2 WIDTH

Given: Length 5 inches

P = 2(5 in) + 2w
P = 10 in + 2w

Perimeter is dependent in both length and width. Changes in any length of width will automatically change perimeter.

For find width using the perimeter formula:

P = 10 + 2w
P - 10 = 2w
(P-10)/2 = w
P/2 - 5 = w

w = P/2 - 5

If the perimeter and length is given, you can use the derived formula to solve for width.

Simplify your answer. 10^1+10^0

artcher [175]

Pemdas
exponent first
remember that x^0=1
basically anything to the 0 poiwer is 1

so
10^1=10
10^0=1
now we have 10+1=11

I need the answer to these, to be right, and you got to show the work on how you got the answer because if not I’ll get them wro

alexira [117]

A: $\frac{5}{3} = \frac{N}{12}$
Multiply both sides by 12
Answer: $N = 20$

B: $\frac{7}{2} = \frac{42}{N}$
Multiply both sides by 2, $7 = \frac{84}{N}$
Multiply both sides by N, $7N = 84$
Divide both sides by 7,
Answer: $N=12$

C: $\frac{N}{2}= \frac{50}{N}$
Multiply both sides by 2, $N = \frac{100}{N}$
Multiply both sides by N, $N^{2} = 100$
Simplify,
Answer: $N = 10 , -10$

Hope I helped you!
