A table measures x+4 inches long and 5x+12 inches wide. What is the perimeter of the table?

tangare [24]

Answer:

P = 12x +32

Step-by-step explanation:

The perimeter is found by using the formula

P =2(l+w)

We know the length and the width

P = 2(x+4 + 5x+12)

Combine like terms

P = 2(6x+16)

Distribute

P = 12x +32

Solve for x if the Perimeter = 26 14-2x 2x + 1 3x - 1

sergejj [24]

Answer:

x = 4

Step-by-step explanation:

Perimeter of triangle = sum of all sides

Side 1: 14 - 2x

Side 2: 3x - 1

Side 3: 2x + 1

Perimeter= side 1 + side 2 + side 3

26 = 14 - 2x + 3x - 1 + 2x + 1

26 = 14 - 1 + 1 - 2x + 3x + 2x

26 = 14 + 3x

3x = 12

x = 12/3

x = 4

Klio2033 [76]

Answer:

22 miles

Step-by-step explanation:

time must be in hours, hence

15 minutes = $\frac{15}{60}$ = $\frac{1}{4}$ hour

distance = 88 × $\frac{1}{4}$ = $\frac{88}{4}$ = 22 miles
