Answer:
The simplified expression is given as

Step-by-step explanation:
step one:
Given the expression

step two:
First, let us open the bracket we have

step three:
collect like terms we have

step four:
we can now factor out
we have

Answer:
D. (-2, 1).
Step-by-step explanation:
y = 3x + 7
y = -2x - 3
AS the expressions on the right are both equal to y:
3x + 7 = -2x - 3
3x + 2x = -3 - 7
5x = -10
x = -2
Plug this into the first equation:
y = 3(-2) + 7
y = 1.
$50.08, I think. Because you can substitute 3x = $75.12 and solve for x

<span> For this case we have the following decimal number:
0.8888
Since the number has 4 decimal places, then the first thing to do is multiply and divide the number by 10000.
We have then:

Answer: A fraction that represents the decimal 0.8888 is: 1111/1250</span>
If they want you to find the perimeter I guess you add all sides so 9+9+9+9+30 = 66
