2b^2 - 3b + 4a^2....a = -6, b = 8

2(8^2) - 3(8) + 4(-6^2) =
2(64) - 24 + 4(36) =
128 - 24 + 144 =

B) Alfredo said that Angle 7 and Angle 6 are congruent and that would prove Line m
malfutka [58]

Answer:

Yes if Angle 7 and angle 6 are linear pairs in angles created by a straight line that cuts through parallel lines.

Step-by-step explanation:

Remember that two parallel lines that are cut by a transveral will create 8 angles, which will be similar to each other. Making four pairs of congruent angles means that they will be exactly the same angle located in different parts of the system. So if angles 6 and 7 are congruent, and the lines are cut by a transversal, then the lines are parallel.

Janelle wrote the matrix addition below. Which statement is true?
Sonja [21]

Option A is correct.

Step-by-step explanation:

We need to identify which statement is true in matrix addition.

In matrix addition we just add the corresponding elements.

In the options given only Option A is correct i.e, (n+4)-7  = 18

All other options have error in them.

In Option B there should be -12 instead of +12

In Option C there should be -11 instead of 11

In Option D we are not adding corresponding entries.

So, Option A is correct.
