Which of the following is equal to the rational expression when x -2 or -1? x^2-4/(x+2)(x+1)

Orlov [11]

Answer:

(x+2)(x+1)

Step-by-step explanation:

Assuming im interpreting this correctly, it should be (x+2)(x+1), since if you plug in -2 and -1, it will give you 0, which is the answer.

A local car wash is open 8 hours each day. It uses 1/3 of a container of wax for each car. The car wash waxes an average of 8 1/

sweet-ann [11.9K]

Answer:

22.67 containers.

Step-by-step explanation:

The number of cars washed is the average by the total hours worked:

$C_{total}=\bar xt,\bar x=8.5,t=8\\\\C_{total}=8.5\times 8=68$

Given that each car uses 1/3 tin of wax, the total containers is calculated as:

$Containers=\bar x_c n,n=68,\bar x_c=\frac{1}{3}\\\\=\frac{1}{3}\times 68\\\\=22.67$

Hence, the car wash uses 22.67 containers of wax per day.

In circle A shown, BC || DE , mBC=58° and mDE=142°. Determine the measure of ZCFE . Show how you arrived at your answer. CORRECT

scoray [572]

We have been given an image of a circle A, where BC || DE , mBC=58° and mDE=142°. We are asked to find the measure of angle CFE.

Since segment DC is parallel to segment DE, so measure of arc BD will be equal to arc CE.

$\widehat{BD}=\widehat{CE}$

We know that sum of all arcs of a circle is equal to 360 degrees. So we can set an equation as:

$\widehat{BD}+\widehat{CE}+\widehat{BC}+\widehat{DE}=360^{\circ}$

Since $\widehat{BD}=\widehat{CE}$ , so we will get:

$\widehat{CE}+\widehat{CE}+\widehat{BC}+\widehat{DE}=360^{\circ}$

$2\widehat{CE}+\widehat{BC}+\widehat{DE}=360^{\circ}$

$2\widehat{CE}+58^{\circ}+142^{\circ}=360^{\circ}$

$2\widehat{CE}+200^{\circ}=360^{\circ}$

$2\widehat{CE}+200^{\circ}-200^{\circ}=360^{\circ}-200^{\circ}$

$2\widehat{CE}=160^{\circ}$

$\frac{2\widehat{CE}}{2}=\frac{160^{\circ}}{2}$

$\widehat{CE}=80^{\circ}$

Therefore, the measure of arc CE is 80 degrees.

We can see that angle CFE is inscribed angle of arc CE, so measure of angle CFE will be half the measure of arc CE.

$\angle CFE=\frac{80^{\circ}}{2}$

$\angle CFE=40^{\circ}$

Therefore, the measure of angle CFE is 40 degrees.
