Answer:
To make given quadratic equation a whole number , we have to add 6 in the equation.. (3 x - 4 )²
Step-by-step explanation:
The given quadratic equation is
9 x² - 24 x + 10 = 0
(3 x )² - 24 x + 10 = 0
(3 x )² - ( 2 × 3 x × 4 ) + 10 = 0
Now if we add 6 to the equation , it will become whole square as (a + b)²
I.e (3 x )² - ( 2 × 3 x × 4 ) + 10 + 6 = 0
Or, (3 x )² - ( 2 × 3 x × 4 )+ 16 = 0
Or, 9 x² - 24 x + 16 = 0
Or, (3 x - 4 )² = 0
Hence to make given quadratic equation a whole number , we have to add 6 in the equation.. Answer
Answer:
38.5
Step-by-step explanation:
Lets say, first number = x
Second number = 3x+7
Total = 49
(x)+(3x+7)= 49
4x+7 = 49
4x = 42
x = 42/4
x= 10.5
x= 10.5
3x+7 = 3(10.5)+7 = 38.5
Hope this helps!!
