BRAINLIEST ASAP! PLEASE HELP ME :)
Nitella [24]

The answer is [ ∠A ≅ ∠A; A F/AB = AG/AC = 3 ]

Both triangles are the same just different sizes.

The length of A F is 9 units. The length of AB is 3 units.

To find the scale factor, just divide.

9 / 3 = 3

The length of AG is 6 units. The length of AC is 2 units.

To find the scale factor, just divide.

6 / 2 = 3

The only logical answer is B because the ratio's are written to where when you solve them, you get the scale factor 3.

Best of Luck!

SOMEONE PLEASE HELP!!
Mazyrski [523]

Answer:

x = 18

Step-by-step explanation:

the sum of any exterior angle is equal to the sum of any two interior angles

3x-11 + 5x+14 = 9x-15

8x + 3 = 9x - 15

3 = x - 15

x = 18

Find the linear equation in slope intercept form that passes through the points (5,3) and (2,-1)
padilas [110]

\bf (\stackrel{x_1}{5}~,~\stackrel{y_1}{3})\qquad  (\stackrel{x_2}{2}~,~\stackrel{y_2}{-1}) \\\\\\ slope =  m\implies  \cfrac{\stackrel{rise}{ y_2- y_1}}{\stackrel{run}{ x_2- x_1}}\implies \cfrac{-1-3}{2-5}\implies \cfrac{-4}{-3}\implies \cfrac{4}{3} \\\\\\ \stackrel{\textit{point-slope form}}{y- y_1= m(x- x_1)}\implies y-3=\cfrac{4}{3}(x-5)\implies y-3=\cfrac{4}{3}x-\cfrac{20}{3} \\\\\\ y=\cfrac{4}{3}x-\cfrac{20}{3}+3\implies y=\cfrac{4}{3}x-\cfrac{11}{3}

The price is 2.25, I found that answer by dividing 27 and 12 for that it would be 12p=27 divide 12 from both sides, p=2.25
