Answer: g(f(x)) = 4x^2 - 4x - 3</h3>
Work Shown:
g(x) = x^2 - 4
g(f(x)) = ( f(x) )^2 - 4
g(f(x)) = ( 2x-1 )^2 - 4
g(f(x)) = (2x-1)(2x-1) - 4
g(f(x)) = 4x^2-2x-2x+1 - 4
g(f(x)) = 4x^2 - 4x - 3
Your answer should be c, or 12 5/6. you would add 1/3 and 1/4 to get 7/12, then multiply it by 22 to get the mixed fraction.
Answer:
<h2>1) B. 1 1/32</h2>
<h2>2) A. 1.8</h2>
Solution:
2 3/4 as an improper fraction is 11/4.
2 2/3 as an improper fraction is 8/3.
11/4 ÷ 8/3
11/4 ÷ 3/8 (reciprocal method)
11/4 × 3/8 (change the operation to multiplication)
11/4 × 3/8 = 33/32 (multiply)
33/32 ⇒ 1 1/32 (simplify)
1 4/5 as an improper fraction is 9/5.
9/5 ⇒ 1.8
Multiply the area of all sides (10*5)*2+(10*4)*2+(4*5)*2 to get 220 in^2
Answer:
d = 5/8f
Step-by-step explanation:
You have the ratio 4d = 2 1/2f, so all you have to do is simplify this equation:
4d = 2 1/2f
divide both sides by 4
d = 5/8f.
