Answer:
According to me it should be, -2x² + 12x - 7
Step-by-step explanation:
you gotta multiply "-" between two equations by the second equation which simplifies to (x² + 5x - 6) + (-3x² + 7x - 1). Now if the two equations are simplified together:
⇒ x²- 3x² = -2x²
⇒ 5x + 7x = 12x
⇒ (-6) + (-1) = -7
Putting it all in one equation will result in: -2x² + 12x - 7
Hope this helps, good luck!

The image shows parallel lines cut by a transversal. The expressions represent unknown angle measurements. What is the value of x?
Answers
Answer:
x = 7
Step-by-step explanation:
The 2 angles are adjacent and sum to 180° , that is
11x + 8 + 12x + 11 = 180
23x + 19 = 180 ( subtract 19 from both sides )
23x = 161 ( divide both sides by 23 )
x = 7

This is because in order to find the value of x you need to do inverse operations. So since this is a multiplication problem you need to do division to find the value of x. 28 divided by 4 = 7. And that’s pretty much it!

A county has the following rule for voting: "Citizens under the age of 18 are not allowed to vote."
Part A: Write an inequality to show the age of citizens who are allowed to vote.
Part B: Describe in words how you can show the solution to this inequality on a number line.
Answers
Answer: Citizens under the age of 18 are not allowed to vote. This means that 18 is included within the ones that can vote.
let x = the citizens under the age of 18
x < 18 is your inequality (Part A)
For the solution, because it does not include 18, you'll use an open dot (a non-filled in circle) placed on 18, and going to the left (less than).

Amanda covers the outside of a box, shown in the diagram below, with decorative paper for a school project. The top of the box is open.
If the paper costs $0.03 per square inch what is Amandas total?
Answers
Answer:
C. $4.38
Step-by-step explanation:
To find out how much paper she covers the box with, you need to find the area of each of the rectangles covered by the box.
First, find the area of the side closest to you.
3 x 8 = 24 in^2
Since the side opposite to it is equivalent, they are both 24 in^2, so multiply 24 by 2:
24 x 2 = 48 in^2
Now, find the sides on the left and right (equal in size).
7 x 3 = 21
21 x 2 = 42 in^2
Finally, find the bottom. There is no top, so there's no need to multiply this one by 2.
8 x 7 = 56 in^2
Add up the sides:
56 + 42 + 48 = 146 [tex]in^2[/tex]
Multiply 146 by 0.03:
146 x 0.03 = 4.38
$4.38
