Answer:
CD = 5
Step-by-step explanation:
AC = 5
BC = 7
∆ACB ≅ ∆DCE, therefore,
AC = CD,
BC = CE, and,
AB = DE
Thus,
AC = CD = 5
CD = 5
F(x) = 2x² + x - 3
g(x) = x - 1
(f - g)(x) = (2x² + x - 3) - (x - 1)
(f - g)(x) = 2x² + (x - x) + (-3 + 1)
(f - g)(x) = 2x² - 2
The answer is D.
So you would multiply if it has the word of in the problem right?
Answer:
I’m assuming you’re talking about what percentage was taken off, so in that case the answer would be approximately 20.6%
Step-by-step explanation:
67.5/85 X/100
cross multiply then divide by 100 to find for x and you get 79.4117
then, subtract this number from 100 and you will get 20.6%
Answer:
Step-by-step explanation:
Area is half base × height
If area = 140 and height = 20 inches
base =140 ÷ 20 = 7 × 2 = 14 inches
