<h3>
Answer: x^2 + 6</h3>
Work Shown:
(f o g)(x) = f(g(x))
f(x) = x + 7
f( g(x) ) = g(x) + 7 ... replace every x with g(x)
f( g(x) ) = x^2-1 + 7 .... plug in g(x) = x^2-1
f( g(x) ) = x^2 + 6
(f o g)(x) = x^2 + 6

Answer:
1) 
2) 
Step-by-step explanation:
You can convert he mixed numbers to improper fractions:
1. Multiply the whole number part by the denominator of the fraction.
2. Add the product obtained to the numerator.
3. The denominator does not change.
Then:

Observe that, in each subtraction, the denominators are equal, then you can rewrite the denominator and subtract the numerators:

Divide 15 by 4. The quotient will be 3 and the remainder 3.
Then:

Answer:
It is a vowel only when it teams up with an <a>, <e>, or <o> to spell a single sound—as in the words draw, few, and low. So the letter <w> is a vowel only in the two-letter teams <aw>, <ew>, and <ow>. Everywhere else <w> is a consonant
Step-by-step explanation:
X^2 - 2x + 4
= (x - 1)^2 - 1 + 4
= (x - 1)^2 + 3
