Answer:
(x + 3)(x + 5)
Step-by-step explanation:
The given expression is x^2 +8x + 15
Now find the factor of 15 such that when you add the factors, we have to get 8
The right factors of 15.
5 * 3 = 15
5 + 3 = 8
The right factors are 3 and 5.
x^2 + 8x + 15 = (x + 3)(x + 5)
Therefore, x^2 + 8x + 15 = (x + 3)(x + 5)
Thank you.
Start with the sum of x and 9, giving the expression
This is divided by 2 so
This equals 3x so the equation is
This can the be solved.
Multiply both sides by 2 to get
Then take x from both sides
Divide by 5 to get the value for x
Volume of a cone = (1/3) x Area of the base (B) x height(h)
V = (1/3)·420·180
= 25200 mm³
Answer:
3:a 4:b
Step-by-step explanation:
if 5^2 x 5^4 you add the exponents so then it would be 5^6
