Answer:
2x^2x(x^+3x-2)
Step-by-step explanation:
Answer:
x< 10
Step-by-step explanation:
To start the absolute difference between 20 and 5 is 15. Next, write out an equation for the problem:
x * 1.5 < 15,
Then divide by 1.5 on both sides...
Boom! x < 10.
Answer:
98
Step-by-step explanation:
Answer: x=3 and y=−2
Step-by-step explanation:
x=−2y−1;4x−4y=20
Step: Solve x=−2y−1 for x:
Step: Substitute−2y−1 for x in 4x−4y=20:
4x−4y=20
4(−2y−1)−4y=20
−12y−4=20(Simplify both sides of the equation)
−12y−4+4=20+4(Add 4 to both sides)
−12y=24
−12y
−12
=
24
−12
(Divide both sides by -12)
y=−2
Step: Substitute−2 for y x=−2y−1:
x=−2y−1
x=(−2)(−2)−1
x=3(Simplify both sides of the equation)
43.96
Explanation:
C=2pi(r)
C=2pi(7)
C=14pi
14 x 3.14 = 43.96
