To solve this, we need to use the distributive property for the right side of the equation.
-2(7 + 2k). To do this, we multiply the outside number by the inside number(s).
-2(7) + -2(2k) = -14 + (-4k)
Now our equation is 3k = -4k -14.
Add 4k to both sides to get k on one side.
7k = -14
Divide by 7 to get k.
k = -2.
I hope this helps!

How can you construct perpendicular lines and prove theorems about perpendicular lines
omeli [17]

Answer:

See descriptions below.

Step-by-step explanation:

To construct a perpendicular bisector, draw a line segment. From each end of the line segment, draw arcs above and below which intersect from each side. Be sure to maintain the same radius on each. Where the arcs intersect above and below, mark points. Connect these two points. This is a perpendicular bisector.

To prove theorems about parallel lines, use angle relationships. For instance, when two parallel lines are cut by a transversal, specific angle are congruent. When these relationships are congruent, you must have parallel lines:

  • Alternate Interior
  • Alternate Exterior
  • Corresponding Angles
  • Same side interior add to 180

A, O and B lie on a straight line segment.
Dafna11 [192]

Answer:

x = 36

Step-by-step explanation:

the 3 angles form a straight angle and sum to 180°

sum the 3 angles and equate to 180

3x + x + x = 180 , that is

5x = 180 ( divide both sides by 5 )

x = 36

Evaluate each expression using the values m = 7, r = 8, and t = 2.
user100 [1]

So I'll walk through the first 2. Then please try the other ones and let me know if you run into more problems.

5m-6

If m is equal to 7, then replace m with 7.

5(7)-6

5x7=35 so the expression is now 35-6. Solve.

35-6=29

So that was the first one.

4m+t

We just do what we do with the first problem.

4(7)+(2)

4x7=28 so the expression is 28+2.

28+2=28

---

hope it helps

p.s. When there is subtraction, add. When there is division, multiply to cancel that out. When there is multiplication, divide to cancel. etc.
