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:
18
Step-by-step explanation:
Product of 7 and a number is 126.
Let's form the equation,
→ 7 × x = 126
The required value of x will be,
→ 7 × x = 126
→ x = 126/7
→ [ x = 18 ]
Hence, the number is 18.
Answer:
Today's price P must be 74% (100% - 26%) of yesterday's price Y. P = $555 = 74%*Y = 0.74*Y. Y = $555/0.74.
