Hello Alondra,

To solve this problem, you have to write a proportion using the ratios formed by the similar triangles.

Or proportion can be:
x/(x+2) = 10/15

Cross multiply to solve it:
10x + 20 = 15x
20 = 5x
4 = x

The value of x is 4.

I hope this helps,

Given f(x) = x^2+4, does there exist an x-intercept between [-2, 3]. Why or why not. Be sure to include in your discussion the I

Anna35 [415]

The x-intercepts are the values of x for which f(x) = 0.
x^2 + 4 = 0
x^2 = -4
x= ±√(-4), which are not real numbers. f(x) does not have an x-intercept.
