Answer:
(1) x^2 is greater than 1.
(2) x is greater than -1.
(1) x^2 is greater than 1 --> x2>1x2>1 --> x<−1x<−1 or x>1x>1. Sufficient.
(2) x is greater than -1 --> x>−1x>−1. Not sufficient.
Answer:
156
Step-by-step explanation:
While solving we will have to use the area formula of the rectangle, which is :A=w*l ; length*width=A.
Steps:
1)let’s consider that the shape is a full rectangle. => 16*12=192.
2)9*2=18 -> 18*2=36
3)192-36=156.
Answer: 20 ft³
Step-by-step explanation:
volume of triangular pyramid = 
- b = base area = 10 ft
- h = height = 6 ft
Therefore, the volume is:
Y>3 only rules out B. B,D,E,F all satisfy 2x<y. So
ANSWER: D E F
