Line n intersects lines 1 and m, forming the angles shown in the diagram below.
bija089 [108]

Answer:

B. 4.5

Step-by-step explanation:

(6x + 42)° and (18x - 12)° are alternate interior angles. If line l is parallel to line m, therefore,

6x + 42 = 18x - 12

Solve for the value of x. Combine like terms.

6x - 18x = -42 - 12

-12x = -54

Divide both sides by -12

-12x/-12 = -54/-12

x = 4.5

Therefore, x = 4.5 would prove lines l and m are parallel to each other.

Which choice is equivalent to the quotient below when. The problem is in the photo below.i am scared please
NeTakaya

Hello from MrBillDoesMath!

Answer:

Choice C, sqrt(3-x)

Discussion:

Have no fear, MBill is here!

The quotient is

sqrt (9-x^2)  / sqrt( 3+x)  =         => as sqrt(a)/sqrt(b) = sqrt(a/b), b <> 0

sqrt (   (9-x^2)/( 3+x) )  =             => as 9 - x^2 = (3-x) * (3+x)

sqrt (  (3-x)(3+x) /(3+x) ) =           => cancel (3+x) from num. and denom.

sqrt( 3-x)

This is Choice C

Note the domain restriction -3 < x < = 3 guarantees that division by zero can't happen.

Thank you,

MrB
