Answer:

C) 4(a + b + 2)

Step-by-step explanation:

In order to determine which equations is not equivalent to 2(2a + b) + 8, we need to solve the equation and match it with the options which are as follows:

A) 4a + 2b + 8

B) 2(2a + b + 4)

C) 4(a + b + 2)

D) 4a + 2(b + 4)

Therefore the equation, 2(2a + b) + 8 = 4a + 2b + 8

The first one 4a + 2b + 8 does match the equation mentioned in question.

The second one 2(2a + b + 4)  = 4a + 2b + 8, therefore this is also equivalent.

The third one 4(a + b + 2)  = 4a + 4b + 8. This one however is not equivalent to 2(2a + b) + 8 = 4a + 2b + 8.

The fourth one 4a + 2(b + 4) = 4a + 2b +8, this one is equivalent to 2(2a + b) + 8 = 4a + 2b + 8.

Hence, C) 4(a + b + 2)  is the only one that is not equivalent to the equation 2(2a + b) + 8

Directions: Solve for x.<br> Please help
aksik [14]

Answer:

Step-by-step explanation:

Since the whole right side of that triangle is equal to 28 and the lower portion is 21, then we know the upper portion is 7. Set up a proportion using those sides and the fact that the 2 triangles are similar:

\frac{7}{21} =\frac{x}{18} and cross multiply to get

21x = 126 and

x = 6

Two parallel lines are _____ coplanar.
dimulka [17.4K]

Answer:

1. always

2. sometimes

Step-by-step explanation:

Two lines are coplanar if they lie in the same plane or in parallel planes. There is  ALWAYS a plane which contains two parallel lines (see first attached image for details).

Two lines that lie in parallel planes are sometimes parallel. For example, see at second image. Planes \alpha and \beta are parallel. Consider pair of lines a and a_1 - they are parallel, but if you consider the pair of lines a and b_1, you can see they are not parallel.
