We know that
area of triangle=b*h/2
b=(x-2) m
Area=(x²-4) m²
h=?
(x²-4)=(x+2)*h/2
but remember that
(x²-4)=(x+2)*(x-2)
so
subsititute
(x+2)*(x-2)=(x+2)*h/2
(x-2)=h/2
h=2*(x-2)
the answer is
<span>the height of a triangle is 2*(x-2)</span>
Answer:
-1 < x ≤ 3
Step-by-step explanation:
group:
-6 < 4x - 2
4x - 2 ≤ 10
group:
-6 + 2 < (4x-2) + 2
(4x-2) + 2 ≤ 10 + 2
Answer:
40
Step-by-step explanation:
8 * 5 = 40
D) 24/65 because it represents the number of players with 1-5 years of experience out of the overall total interviewed.
E) 3/11 because out of the eleven rookies, only three of them were under 200 lbs.
F) out of the 8 that reported to be under 200 pounds, only 3 were rookies, so the probability is 3/8
