1. Write the factors
(x+3)(x-6) = 0
2. Multiply the factors to get the answer in standard form
x^2 + 3x - 6x - 18 = 0
3. Simplify
x^2 - 3x - 18 = 0
Answer:
11253.76
Step-by-step explanation:
To find the volume of a cylinder we must utilise the volume of cylinder formula which is
→ Volume of cylinder = π × r² × h
Where 'r' is the radius and 'h' is the height so let's start substituting in the values,
→ Volume of cylinder = π × r² × h
⇒ Substitute in 3.14 for π, 14 for 'h' and 16 for 'r'
→ Volume of cylinder = 3.14 × 16² × 14
⇒ Simplify
→ Volume of cylinder = 11253.76
So a cylinder has a height of 14 millimetres and a radius of 16 millimetres has a volume of cylinder 11253.76 inches³
Answer:
D) x = 3 , x= 10.
Step-by-step explanation:
Given : x²-13x+30=0
To find : Use the zero product property to find the solutions to the equation.
Solution : We have given
x²-13x+30=0
On factoring
x²-10x -3x +30=0
On taking x common from first two terms and -3 from last two terms .
x ( x - 10 ) - 3( x - 10 ) = 0
On grouping
(x -3) ( x -10) = 0.
By the zero product property
x -3 = 0
x = 3 ,
For x - 10 = 0.
x = 10.
Therefore,D) x = 3 , x= 10.
Answer:
Step-by-step explanation:
21 x 0.07= 1.47
21+1.47=22.47
Total=22.47
