Step-by-step explanation:
The cost per calculator is 5
The shipping cost is 15
Let y = total cost
Let x = number of calculators
y = 5x+15
Answer:
4x^{3} + 6x^{2} -10x -15
Step-by-step explanation:
(2x+3)(2x^{2} -5)
2x × 2x^{2} + 2x× (-5) + 3× 2x^{2} + 3 ×(-5)
=4x^{3} -10x + 6x^{2} -15
= 4x^{3} + 6x^{2} -10x -15
Step-by-step explanation:
Let diameter of the circle be d and radius be r.

Hence radius of the circle is 5 kilometers.
Answer:



Step-by-step explanation:
We can create an equation for this problem by converting the words to an equation.
The <em>flat fee</em> was $119. We then add $75 for every hour worked. This means that this becomes
. Since the total cost was $306.50, the equation is
.
We can now solve for x, the amount of hours worked, to find it’s value.
