The length of the sides of a triangle are x, 2x+2, and 13. If the perimeter of the triangle is 30, what is the value of x?
1 answer:
Add all the sides up to equal 30 in an equation because you are given the perimeter. The perimeter is the length around a two dimensional shape. This means the perimeter is the length of all the side lengths added together.
(x) + (2x + 2) + (13) = 30
Combine like terms.
3x + 15 = 30
Subtract 15 from both sides.
3x = 15
Divide both sides by 3.

The equivalent function:
Step-by-step explanation:
The x-intercepts of the given function on the graph can be obtained by equating the function to zero.
This is because on the x-axis, the y-coordinate is zero.
The function that has the same x-intercepts on the graph from the given options is:
