Answer:

Step-by-step explanation:

15)  point D=(3,1)

for AB we can see that there is an exact triangle of 2 and 5

so AD =  \sqrt{2^{2} +5^{2} } = \sqrt{29}  and 2(AD) = AB

AB = 2*\sqrt{29}  ( this is an exact answer, leave it with the square root)

16) find CD  length  we know the points at each end so use the distance formula  P1=(-3,4)  P2=(3,1)

Dist. = \sqrt{(3-(-3))^{2} +(1-4)^{2} }

Dist. =\sqrt{45}   = \sqrt{9*5}  = 3\sqrt{5} ( exact answer leave the square root )

CD = 3\sqrt{5}

17)  1/3 of the way along CD from D towards C is where the centroid is.. I just happen to know that from doing this too often.  :/

so that mean  \frac{1}{3} * 3\sqrt{5}   is the distance from D to the centroid or \sqrt{5}

also b/c I happen to know.. :/    c = \sqrt{1^{2}+ 2^{2} } = \sqrt{5}  off the top of my head I can see that the point (1,2) is our centroid for this object.. they made it really easy  ... okay..  relatively easy. .:D  

Centroid = (1,2)

In a certain​ fraction, the denominator is less 7 than the numerator. If 3 is added to both the numerator and​ denominator, the
Aleksandr-060686 [28]

Answer:

original fraction =12/5

Step-by-step explanation:

let x = numerator

therefore

   x+3/x-7+3 =15/8

    x+3/x-4 =15/8

      8(x+3)=15(x-4)

      8x+24=15x-60

       84=7x

        84/7=x

        12=x

therefore original fraction = 12/5
