Answer:

Step-by-step explanation:

x = width

4x - 16 = length

x + x + (4x - 16) + (4x - 16) = 68

= x + x + 4x - 16 + 4x - 16 = 68

= 10x - 32 = 68

= 10x = 100

= x = 10

width = 10 feet

length = 24 feet

Length=24, Width = 10

2L + 2W = perimeter

The length is 4 times the width minus 16 or 4w-16
So substitute L value into equation

2(4w-16)+ 2W = 68
8w-32+2w=68
10w=100
W=10

Width is 10

Length is 4w-16
Length = 4(10)-16
Length = 40-16
Length = 24

Answer:

Option 2: 2x + 2 = 72

Step-by-step explanation:

First odd: x

Next odd: x + 2

x + (x + 2) = 72

2x + 2 = 72

Because the difference between two consecutive odd numbers is 2.

e.g 3 and 5

A bicycle is on sale at $12 more than half of the regular price. If the sale price is $75, find the regular price.
konstantin123 [22]
So 12 more than half the regular price.
let's let p be the original price.

\frac{1}{2} p + 12 = 75
right?
Now you just have to solve from there.

viva [34]

Step-by-step explanation:

Given g'(x) = g^{-2}, x> 0\ g(1) = 0 \ and \ g(2) = 0

To get g(x), we will have to integrate g'(x)

g(x)  = \int\limits {x^{-2}} \, dx\\ g(x)  = \frac{x^{-2+1}}{-2+1} + C\\ g(x) = -x^{-1} + C\\g(x) = -x^{-1} + C\\

If g(1) = 0, this means at x = 1, g(x) = 0

0 = -1⁻¹ + C

C= 1

Substitute C = 1 into the function

g(x) = -x⁻¹ + 1

If g(2) = 0, this means at x = 2, g(x) = 0

0 = -2⁻¹ + C

C= 2⁻¹

C =  1/2

Substitute C = 2 into the function

g(x) = -x⁻¹ + 1/2
