Start by distributing the exponent to each of the terms in (2u)^{3}.  This will become 2^{3} u^{3}, and 2^{3} =8.  Now, the expression is:

\frac{2u^{3} v^{2} }{8u^{3} * u^{2} }.


We can now simplify the bottom to read: 8u^{5} because when multiplying variables raised to an exponent, we add the exponents.  The expression now looks like:

\frac{2u^{3} v^{2} }{8u^{5} }


The 2/8 simplifies to 1/4:

\frac{u^{3} v^{2} }{4u^{5} }


Now, we have two u terms on the top and bottom.  When dividing variables raised to an exponent, we subtract the exponents.  However, since 3-5=-2, the term will be on the bottom to avoid the negative exponent.  The final answer is:

\frac{v^{2} }{4u^{2} }


Hope this makes sense!!

Lines x and y are parallel and are cut by the transversal b. If the measure of angle 1 is 57°, what is the measure of angle 6? E
lana [24]

Answer:

\angle6=123

Step-by-step explanation:

Given

Lines x and y

Transversal b

\angle 1 = 57

Required

Find \angle 6

From the attachment, \angle1 and \angle7 are vertically opposite.

This means that

\angle 1 =\angle 7 = 57

Similarly

\angle 7  and \angle 6 are supplementary angles

So:

\angle7 + \angle6=180

Make \angle6 the subject

\angle6=180-\angle7

\angle6=180-57

\angle6=123

The relationship between \angle1 and \angle6 is that they are supplementary angles because:

\angle6+ \angle1=180

Write an equation for the line passing through the points (2,4) and (2,7).
Nataly_w [17]

Answer:

x=2

Step-by-step explanation:

Since the points (2,4) and (2,7)  are on the line whose equation is x = 2,

The equation of the line passing through them is hence x = 2
