Okay so the small triangle has sides that are 3 units, 4 units and 5 units long
the larger triangle has sides that are 6 units, 8 units and 10 units long so using this information we can see that the larger triangle is twice the size of the small triangle.
Hope this helps :)

Answer:
x = 3 is extraneous
Step-by-step explanation:
Given
= x - 5 ( square both sides to clear the radical )
4x - 8 = (x - 5)² ← expand using FOIL
4x - 8 = x² - 10x + 25 ( subtract 4x - 8 from both sides )
0 = x² - 14x + 33 ← in standard form
0 = (x - 11)(x - 3) ← in factored form
Equate each factor to zero and solve for x
x - 11 = 0 ⇒ x = 11
x - 3 = 0 ⇒ x = 3
As a check
Substitute these values into the equation and if both sides are equal then they are solutions
x = 11
left side =
=
= 6
right side = 11 - 5 = 6
Thus x = 11 is a solution
x = 3
left side =
=
= 2
right side = 3 - 5 = - 2 ≠ 2
Thus x = 3 is an extraneous solution
we know that
The simple interest formula is equal to

where
I is the simple interest
P is the principal ( the amount borrowed or deposited)
r is the interest rate
t is the time
in this problem we have

Substitute the values in the formula above


therefore
<u>the answer is</u>
The amount of interest earned is equal to
