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:
-5 -√8 or ≈ -7.83
Step-by-step explanation:
<u>Solving the quadratic equation, to find its roots:</u>
- x^2 + 10x + 25 = 8 ⇒ The left side is perfect square
- (x+5)^2=8 ⇒ Getting square root of both sides
- x+5 = ± √8 ⇒ There are 2 roots
- x = - 5 ± √8
<u>The smallest root is:</u>
I'm not entirely positive about it but I think it might be N=CxP..
Answer:
Hello! answer: w = 23.5
Step-by-step explanation:
It is asking what multiplied by 2 will get 47 so all we have to do is 47 ÷ 2 to get our answer so...
47 ÷ 2 = 23.5 so w = 23.5 Hope this helps!
