What is the length of AC?
PLEASE HELP

136

Step-by-step explanation:

The triangles are similar so we can use ratios

3          x

=

51         144-x

Using cross products

3(144-x) = 51x

Distribute

432 - 3x = 51x

Add 3x to each side

432 = 54x

Divide each side by 54

432/54 = 54x/54

8 = x

We want the length of AC

AC = 144-x

     = 144-8

     =136

D. 136

Step-by-step explanation:

Since these two triangles are similar by AA:

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

answer: integers are just whole numbers: positive, negative, and zero.

i = {-∞, -2, -1, 0, 1, 2, 3, ∞}

let x = 1st integer

let y = 2nd integer

x = 3y + 17   {equation 1}

xy = -24         {equation 2}

substitute 3y+17 in place of x n equation 2

and solve for y.

(3y+17)y = -24

3y2 + 17y = -24

3y2 + 17y + 24 = 0

from quadratic equation:

y = [-17±√(172-4(3)(24))]/(2(3))

y = (-17 ±√1)/6

y = (-17+1)/6   or     y = (-17-1)/6

y = -16/6           or     y = -18/6

y = -2 2/3         or   y = -3

since we are dealing with

y = -3

x = 3y+17 = -9+17 = 8

the integers are -3, 8
