Answer: 30 in.
Step-by-step explanation:
If it's an equilateral triangle, all sides are the same length. Therefore
3x + 15 = 7x - 5
x = 5
After figuring out x = 5, replace the x with five and solve the equation.
3(5) + 15 = 30
7(5) - 5 = 30
Now that we know the length of two sides, we can state that the third side-length <u>also</u> equals 30 inches because it is an equilateral triangle, meaning all sides are congruent/ the same.
To find the x-int, you have to replace 0 with y
4x-3(0)=6x+(0)
4x=6x
none
no x-int
Answer:
y=25x is correct option .
