Answer:
{x +4} {x+3} =0
Step-by-step explanation:
The equation is given as :
x² + 7x + 12 =0
Find multiples of 12 that can add to give +12 ------3 * 4
The equation can then be written as;
x² + 3x + 4x + 12 = 0 ------factorize
x{ x + 3 } + 4 { x +3 } = 0
{x+4 } {x + 3} = 0
Answer : {x +4} {x+3} =0
Answer:
1st page is 2
2nd page is -2
Step-by-step explanation:
3 x -4 = -12
-12 / -2 = 2
-6 / 3 = -2
negative time a negative is a positive and a positive times a negative is a positive

Answer:
3.6
Step-by-step explanation:
There are 144 in² in 1 ft².
(518 in²) × (1 ft²)/(144 in²) ≈ 3.597222... ft² ≈ 3.6 ft²
Answer:
Step-by-step explanation:
So first you got to simlipy both sides of the equation.Like this:
10x-3x+2=6x+6
7x+2=6x+6
Then you have to move the variables to one side and the other nums to the other side:
7x-6x = 6 -2
Then you have to simplify.
x = 4
Hoped it helped!
(2,5) (9,2)
Before finding slope intercept form (y=mx+b) we must find point slope form. Point slope for is y-y1 = m(x-x2) where m is slope and (x1,y1) is a coordinate pair on the line. To find slope we use the formula (y2-y1)/(x2-x1). Since we have two points given, we simply plug them in to this equation.
(5 - 2)/(2 - 9) = 3/- 7 so m = -3/7.
Now we can fill in the point slope equation using either coordinate pair provided. Will be using the one with smaller numbers (2,5). Plug your values in!
y - 5 = -3/7(x-2)
Now to get to slope intercept form you simply multiply or distribute and move over the 5.
y - 5 = -3/7x + 6/7 ---- Now add 5 or 35/7 to both sides
y = -3/7x + 6/7 + 35/7 ----- Simplify to get a final answer if y = -3/7 + 41/7 which is the second choice on the screen.
