Answer:

(x+2)(x-6), factors are -6 and 2

Step-by-step explanation:

x^2 − 4x − 12

we find out factors whose product is -12 and sum is -4

-6 times 2 = -12

-6+2=-4

So two factors are -6 and 2

Now we use the factors -6 and 2 to factor x^2 -4x-12

x^2 -6x+2x-12

(x^2 -6x)+(2x-12)

take out GCF, x(x-6) + 2(x-6)

(x+2)(x-6)

(x-6)(x+2)

When you foil it you get x^2+2x-6x-12
After you do this you then add like terms to get x^2-4x-12
Therefore the answer (x-6)(x+2) is correct.

mamaluj [8]

Answer:

$\angle 1 + \angle 2 = 180^o$

Step-by-step explanation:

Given

$\angle 1$ and $\angle 2$

Required

The relationship between them $\angle 1$ and $\angle 2$

From the question, we understand that $\angle 1$ and $\angle 2$ are supplementary

Supplementary angles add up to 180.

So, the relationship between $\angle 1$ and $\angle 2$ is:

$\angle 1 + \angle 2 = 180^o$

Answer:

13/7

Step-by-step explanation:

From the question, we have

3/7 of cherry pie

2/7 of apple pie

3/7 of peach pie

5/7 of blueberry pie

Now we have to add up all of these in order to get the total amount of pie

3/7 + 2/7 +3/7 +5/7

= (3+2+3+5)/7

=13/7

If expressed as a mixed fraction

= 1 6/7

In conclusion, 13/7 pie remains as a fraction of a whole.
