A. No, because -38 isn't a fraction.
2, No because 400 is a real number.
3. Yes because fractions, decimals, and percents are rational numbers.
hope that helped
Assuming we’re talking about a cylinder, whose volume formula is V = pi r^2 h…
It will have a greater effect to change a variable’s value that has a greater power on it.
Changing h from 1 to 2 doubles the volume.
Changing r from 1 to 4 quadruples the volume, because 1^2 = 1 and 2^2 = 4. The effect of the change on r is amplified by the power.
Answer:
x=√139-3, x=-√139-3
Step-by-step explanation:
to complete the square, you first move the constant to the other side of the equation-its already done for you!
now, you find the perfect square trinomial. You divide the b value by 2, then square it: 6/2=3, 3^2=9.
What you do to one side has to be done with the other.
x^2+6x+9=130+9
now you can factor the square:
(x+3)^2=139
squareroot both sides:
x+3=√139
x+3=-√139
now subtract both sides by 3
x=√139-3
x=-√139-3
Answer:
-5
Explanation:
First, expand.
r + b - 9 × b + g.
If r = 9, b = 5, and g = -6, this would be the answer:
9(r) + 5(b) - 9 = 5
×
5(b) + -6(g) = -1
5 × -1 = -5
