Subtract -9 from both sides.
x2+6x−(−9)=−9−(−9)
x2+6x+9=0
Factor left side of equation.
(x+3)(x+3)=0
Set factors equal to 0.
x+3=0 or x+3=0
x=−3
Answer:
x=−3
To solve for the volume of a spherical ball, we use the formula,
V = (4<span>πr^3)/3
The given radius of 3x10^2 centimeters converts to 3 meters. Solving for the volume,
V = (4</span>π)x(3^3)/3 = 36<span>π m^3
</span>Thus, Sara is trapped in a spherical ball with a volume of 36<span>π m^3.

10x^4y^3 - 5x^3y^2 + 20x^2y....first, find the GCF of ur coefficients (numbers)....it is 5...now find the lowest exponents of x, which is x^2...and now find ur lowest exponent of y, which is y
so ur GCF is : 5x^2y
Answer:
w=4
Step-by-step explanation:
18+3w=30
3w=30-18
3w=12
w=4
Answer:
Step-by-step explanation:
To get the answer just use the numbers from the table which you have stated and you are right, you do get a long decimal.
5.69*10^26 / 6.42 * 10^23 = 886.29
which rounds to 886
