A rectangle is ( x + 6 ) meters long and ( 2 x − 1 ) meters wide. Which expression represents the PERIMETER of the rectangle?

6x +10

Step-by-step explanation:

Perimeter = 2*(length + width)

 = 2* (x+6 + 2x-1)

=2*(3x +5)

=2*3x + 2*5

=6x + 10

P = 6x + 10

Step-by-step explanation:

Perimeter of a rectangle

= 2(L + W)

Where L = length

W = width

Given

L= (x + 6)

W =(2x - 1)

Perimeter = 2( x+6 + 2x -1)

Simplify the bracket first

P = 2(x + 2x +6 - 1)

P = 2(3x + 5)

Now , expand the bracket

P = 2 x 3x + 2 x 5

P = 6x + 10

3x^3-x^2+6x-9

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
