If you factor the denominator of the left multiplicand...

[(a-4)(a+3)]/[a(a-4)]  you can see that the (a-4)s cancel out leaving:

(a+3)/a

now you have

(a+3)/a * 2a^3/((a+3)(a-1))  so the (a+3)s cancel out leaving:

1/a * 2a^3/(a-1)  which is:

2a^3/(a(a-1))  so now a^1 cancel leaving

2a^2/(a-1)

Sheila can ride her bicycle 6000 meters in 15 minutes. How far can she ride in 2 minutes?
iren [92.7K]
<span>Sheila can ride her bicycle 6000 meters in 15 minutes. 
Forming that into a ratio, that will be 6000 : 15

Doing the proportion for 2  minutes.
6000 : 15 = X : 2

Doing the computation.
6000 / 15 = X / 2
15X = 2 * 6000
15X = 12000
X = 800

So Sheila covered a total of 800 meters in 2 minutes.</span>

What is the y - intercept of y-8 = 2x *
Zielflug [23.3K]

Answer:

(0,8)

Step-by-step explanation:

First, we must arrange this equation into slope-intercept form, or  y=mx+b form.

Equation: y-8=2x

Add 8 to both sides: y=2x+8

Now that the equation is in slope-intercept form, it is easy to find the y-intercept, as it  is just the b-value.

In this case, the b-value is 8, so the y-intercept is (0,8).

Let me know if  this helps!

Suppose the scale factor you will use to enlarge the map is 5:1. What is the approximate area of the park in your enlarged drawi
slamgirl [31]

Answer:

525

Step-by-step explanation:

If the area of the map is 21 and the scale factor is 5:1, both of the dimensions of the flat park are multiplied by 5. If both dimensions are multiplied by 5, then the area is multiplied by (5*5)=25 times. 25*21=525. Hope this helps!
