With the b2+b- 12 your gonna want to do this
b2+b-12
b2+4b-3b-12
which is the sum product
after doing that you wanna common the factors from the two pairs. Which is b2+4b-3b-12 then you do you parentheses around b(b+4)-3(b+4) just like that after you do that then you rewrite it in factored form b(b+4)-3(b+4) you then want to rewrite it to this (b-3)(b+4) after that your solution will be (b-3)(b+4) for the first one.
Answer:
Step-by-step explanation:
Given:
The two points on the line are 
and 
.
The slope of the line joining two points 
and 
is given as:
Here, 
∴ 
Equation of line with a point and slope 
is given as:
Plug in -2 for 
, 3 for 
and -7 for . This gives,
Therefore, the equation of the line in vertex form is .
Let x = our unknown number
10x = 600
Divide by 10 on both sides to isolate the variable x.
x = 600/10
x = 60
600 is 10 times as much as 60.
18 cm^3
1/2 x 4 x 3 = 6
6 x 3 = 18
