Answer:

x=-2, y=-9/2. (-2, -9/2).

Step-by-step explanation:

x=2y+7

3x-2y=3

--------------

3(2y+7)-2y=3

6y+21-2y=3

6y-2y+21=3

4y+21=3

4y=3-21

4y=-18

y=-18/4

simplify

y=-9/2

x=2(-9/2)+7

x=-9+7

x=-2

ycow [4]

Answer:

(x+6)(x+6)

(x+6)^2

Always remember this identity

(a+b)^2 = a^2 + b^2 + 2ab

So, Now take x=a , 6 =b

Substitute above values

x^2 + 36 +2(x)(6)

=x^2 +36 +12x

=x(x+12) +36

explain how you can mentally determine whether 125 x 0.9 is less than, greater than, or equal to 125.
Citrus2011 [14]
Anything times 1 is equal to itself. Anything times less than one is less than itself. Anything times greater than one is greater than itself. Therefore, 125 times .9, which is less than one, is less than 125
