x will represent the side length of the smaller square, so 2x is the side length of the bigger square.
x*x + 2x*2x = 45
x^2 + 4x^2 = 45
5x^2 = 45
x^2 = 9 (Divide by 5)
sqrt(x^2) = sqrt(9)
x = 3
2x = 6 (Multiply by 2)

Answer:
The principal borrow for loan is $1,500 .
Step-by-step explanation:
Given as :
The interest paid on simple interest = s.i = $240
The rate of simple interest applied = r = 4%
The time period for loan = t = 4 years
Let The principal borrow = $p
Now,<u> from Simple Interest method</u>
Simple Interest = 
Or. s.i = 
Or, $240 = 
Or, $240 × 100 = 16 × p
Or, $24000 = 16 × p
∴ p = 
i.e p = $1,500
So, The principal borrow for loan = p = $1,500
Hence, The principal borrow for loan is $1,500 . Answer

Step-by-step explanation:
Answer: Hours by Tina practiced this month is 3 times the hours she practiced last month such that 15 x 3 =45 hours.
Step-by-step explanation:
Given : Duration of Tina practiced piano last month= 15 hours
Duration of Tina practiced piano this month= 45 hours
We can see 45 is a multiple of 15 such that 
Therefore, Hours by Tina practiced this month is 3 times the hours she practiced last month such that 15 x 3= 45 hours.

Answer:
f(g(x)) = -3x^2 -2x -3
Step-by-step explanation:
<u>Given</u>:
f(x) = -x-7
g(x) = 3x^2 +2x -4
<u>Find</u>:
f(g(x))
<u>Solution</u>:
Substitute per the function definitions.
f(g(x)) = f(3x^2 +2x -4) = -(3x^2 +2x -4) -7
f(g(x)) = -3x^2 -2x -3
