Daniel is enrolling for a test prep class. the expression below represents the hourly charges, including the cost for the materials. $30x + $65 1. the constant of the expression represents the a. cost of materials b. cost per hour c. number of hours 2. and the coefficient of x represents the__ a. cost per hour b. cost of materials c. number of hours

Step-by-step explanation:

The given expression is

This is a linear expression in slope-intercept form, where the constant ratio of change is 30, and the y-intercept is at y = 65.

Now, according to the problem, the expression represents the hourly charges, including the cost for the materials.

Therefore, the hourly charge is $30 per hour, where x represents hours, and the cost for materials is $65.

So, the answer to the first question is: A. cost of materials.

And the answer to the second question is: C. number of hours.

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
