Its c I've done this before
X^2+12x-28
(x-2)(x+14)
Solve for x
x-2=0
x=2
x+14=0
x=-14
Answer: The numbers are: <u>x = 34, y = 12</u>
Step-by-step explanation:
Lets say the numbers are x and y. The two equations are:
x+y=46
x= 3y-2
Next you use substitution for x in the first equation which brings you to
3y-2 + y = 46 which simplyfies to:
4y - 2 = 46
4y = 48
48 / 4 = 12
y = 12
Then you plug back y=12 in either of the equation to solve for x:
x = 3y - 2
x = 3(12) - 2 = 36 - 2 = 34
x = 34, y = 12
Answer:
Step-by-step explanation:
(7x-5)(6x+10)=0
42x + 70x - 30x - 50 = 0
82x = 50
x = 50/82
