Answer:
4×(x² - 4x + 2)
Step-by-step explanation:
4x2 - 16x + 8 = 4×x² - 4×4×x + 4×2 = 4×(x² - 4×x + 2)
Answer:
80 pages
Step-by-step explanation:
We can use ratios to solve
168 papers x papers
------------------ = -----------------
21 minutes 10 minutes
168*10 = x * 21
1680 = 21x
Divide each side by 21
1680/21 = 21x/21
80 = x

Only the first statement is true.
Answer:
x = 200/3
Step-by-step explanation:
Apply Thales theorem, we have:
80/(2x) = 60/27
Let's simplify both sides:
40/x = 20/9
or
x/40 = 9/20
Multiplying both sides by 40, we have:
(40/40)x = (20/9)*40
Let's simplify one more time:
x = (20*40)/(9)
or
x = 200/3
Hope this helps!
