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.
1) In this problem, we can see that this is an isosceles right triangle.
2) So, one way of solving it is to make use of the Pythagorean theorem. Note that an isosceles triangle has two congruent sides, so we can write out:
Usually, we rationalize it. But since the question requests the denominator to be a rational one, so this is the answer.

Given an exponential function, say f(x), such that f(0) = 1 and f(1) = 2 and a quadratic finction, say g(x), such that g(0) = 0 and g(1) = 1.
The rate of change of a function f(x) over an interval
is given by
Thus, the rate of change (growth rate) of the exponential function, f(x) over the interval
is given by
Similarly, the rate of change (growth rate) of the quadratic function, g(x) over the interval
is given by
Therefore, the exponential grows at the same rate as the quadratic in the interval <span>
