Answer:

-a^2 - a + 12

Step-by-step explanation:

You only need to find the products of the first and last terms to determine the correct answer:

(-a)(a) = -a^2

(3)(4) = 12

You're looking for an expression with -1 as the leading coefficient and +12 as the constant. There is only one choice like that:

-a^2 - a + 12

Solve for (y)(x)<br> x-y=1<br> 1/2x+y=5

TEA [102]

Using addition

x-y+1/2x+y=1+5
x+1/2x+0y=6
3/2x=6
$\frac{3}{2}x=6$
3x=12
x=4

Using the value of x
x-y=1
4-y=1
y=3

With x as 4 and y as 3, their product is 12
And can be written as (4,3)
