Answer:

     r+5                 r^2+4r-21

-------------- /   --------------------

r^2+5r-14               r-2


         r+5                     r-2

= --------------  x   --------------------

   r^2+5r-14           r^2+4r-21


         r+5                     r-2

= --------------  x   --------------------

   (r+7)(r-2)           (r+7)(r-3)



         r+5                     

= -----------------

   (r+7)^2 (r-3)

Fynjy0 [20]

Answer:

begins the trip with 14 gallons of gas in her car.

The car uses up one gallon of gas every 30 miles.

Let g represent the number of gallons of gas she has left in her tank, and let d

represent the total distance

Step-by-step explanation:d = 30(14 - g)

:

For example, if she uses two gallons, there will be 12 gal left in the tank; g=12

d = 30(14 - 12)

d = 30(2)

d = 60 mi  Here you go

Geometry help please! Match the reasons with the statements.
SSSSS [86.1K]

Given:

∠PRS and ∠VUW are supplementary.

To prove:

Line TV || Line QS

Solution:

Step 1: Given

∠PRS and ∠VUW are supplementary.

Step 2: By the definition of supplementary angles

m\angle {PRS}+m\angle {VUW}=180^{\circ}

Step 3: Angles forming a linear pair sum to 180°

m\angle {PRS}+m\angle {SRU}=180^{\circ}

Step 4: By transitive property of equality

step 2 = step 3

m\angle {PRS}+m\angle {VUW}=m\angle {PRS}+m\angle {SRU}

Step 5: By algebra cancel the common terms in both side.

{m} \angle {VUW}={m} \angle{SRU}

Step 6: By converse of corresponding angles postulate

Line TV || Line QS

Hence proved.

For its 28th anniversary, an Uncles Game store is offering a 28% discount on all board games. What is the discounted cost of the
svetlana [45]

Answer: $23.40

Step-by-step explanation:

   We will find what percent of the normal cost the items are currently.

100% - 28% = 72%

   Now, we will find 72% of $32.50

72% -> 0.72

$32. 0 * 0.72 = $23.40

          The discounted cost is $23.40.
