Answer:
x² + x - 12 = 0
Step-by-step explanation:
Given the solutions are x = - 4 and x = 3, then the factors are
(x + 4) and (x - 3) and the equation is the product of the factors, that is
(x + 4)(x - 3) = 0 ← expand factors using FOIL
x² + x - 12 = 0 ← in standard form
The answer is A. To add fractions, the denominator has to be the same. What number do 9 and 3 share when multiplying ? It is 9.
So multiply 2/3 by 3/3 to get 6/9. And 1/9 by 1/1 to get 1/9. Now add 6/9 with 1/9 which is 7/9
Now add 7/9 with 5/18. 9 and 18 share 18. Multiply 7/9 by 2/2 which is 14/9. Add 14/9 to 5/18 which is 19/18
Answer:
y=21
Step-by-step explanation:
y=7 and x=4 when x=12 thats 3 times 4 so multiply 7 by 3 and you get 21
