Answer:
-The slopes of EF and GH are both.
-Quadrilateral EFGH is a parallelogram because both pairs of opposite sides are parallel.
Step-by-step explanation:
I don't know the step by step process.
Step-by-step explanation:
f(x)=x²-1, f(x-1)=(x-1)²-1
=(x-1)(x-1)-1
=(x²-x-x+1)-1
=x²-2x+1-1
=x²-2x=0
x²=2x
x=2
Answer: 2π ft^2
Step-by-step explanation:
Area of a circle= π x the radius ^2
here your diameter is 4, and the radius is equivalent to half of the diameter so your radius equals 2.
A= π x 2^2
2x + 5 > 9 2x + 5 < - 9
2x > 9 - 5 2x < -9 - 5
2x > 4 2x < - 14
x > 4/2 x < -14/2
x > 2 x < - 7
It would be answer B
Answer:
The answer is
<h2>18</h2>
Step-by-step explanation:
a ∆ b = a² + ab + b²
(3 ∆ 2)
a = 3 b = 2
(3 ∆ 2) = 3² +3(2) + 2²
= 9 + 5 + 4
= 9 + 9
= 18
