Area of a trapezoid is height times the average of the bases,
A= 1/2 h (a + b)
Here we have height h=12 and bases a=30, b=12 so area
A = (1/2) (12) (30 + 12) = 6(42)= 252
Answer: B
Your inverse will be x = -1 .
G(h(x)) = 2(3x+7) - 5
= 6x + 14 - 5
= 6x + 9
Answer:
(x + 1 ≤ 1) ∩ (x + 1 ≥ 1)
Step-by-step explanation:
Here, we have to choose the sets from options which has a solution set of {x I x = 0}
From the given options it is clear that the second option will be the correct option.
Here, (x + 1 ≤ 1) ∩ (x + 1 ≥ 1)
⇒ (x ≤ 0) ∩ (x ≥ 0)
Therefore, the only set of the above intersection of the two sets will be x = 0. (Answer)
