6xy² + 10y²z is the product answer
Step-by-step explanation:
The percentage is 1/2 * 2/5 = 1/5 = 20%.
Ellie's age = 58 years
Genya's age = 2 years
Step-by-step explanation:
Let e represent Ellie's age
and
g be Genya's Age
Then
In six years
Ellie will be e+6 years old and Genya will be g+6 years old
then
Putting g= 8e+42 in equation 1
Dividing both sides by 9
Putting e = 2 in equation 1
Hence,
Ellie's age = 58 years
Genya's age = 2 years

Answer:
V=1472.6
Step-by-step explanation:
Volume of a cone=π*r^2*h/3
The volume of an oblique shape is the same as a non oblique shape. Also, 15/2 is our radius
V=π*r^2*h/3
V=π*7.5^2*(25/3)
V=pi*56.25*8.33333...
V=1472.62155637
V=1472.6
Answer:
x=3
x=−3
Step-by-step explanation:
2x^2 - 5 = 13
Subtract 13 from both sides.
2x^2 - 5 - 13 = 0
Subtract 13 from −5 to get −18.
2x^2 - 18 = 0
Divide both sides by 2.
x^2 - 9 = 0
Consider x^2−9. Rewrite x^2−9 as x^2−3^2. The difference of squares can be factored using the rule: a^2−b^2=(a−b)(a+b).
(x−3)(x+3)=0
To find equation solutions, solve x−3=0 and x+3=0.
x=3
x=−3
