Answer:
Step-by-step explanation:
f(x) = 3x² + 10x - 25
g(x) = 9x² - 25
To find (f/g)(x) divide f(x) by g(x)
That's
Factorize both the numerator and the denominator
<u>For the numerator</u>
3x² + 10x - 25
3x² + 15x - 5x - 25
3x ( x + 5) - 5( x + 5)
(3x - 5 ) ( x + 5)
<u>For the denominator</u>
9x² - 25
(3x)² - 5²
Using the formula
a² - b² = ( a + b)(a - b)
(3x)² - 5² = (3x + 5)(3x - 5)
So we have
Simplify
We have the final answer as

Answer:
you multiply the quotient times the divisor and your awnser should be the same as the dividend
Step-by-step explanation:
Answer:
it does represent the total area
Step-by-step explanation:
Answer:
20%, or 4 questions
Step-by-step explanation:
16 / 20 or 8 / 10 = 80%
What's left over?
100 - 80 = 20
20%
0.1 = 1/10
0.16 = 16/100 = 8/50 = 4/25
0.6 = 6/10 = 3/5
0/6 = 6/10 = 3/5
