A triangle has sides 3x + 7, 4x -9, and 5x + 6. Find the polynomial that represents its perimeter. A. 8x + 4 B. 12x + 13 C. 8x –5 D. 12x + 42 help me

use an equation of ratios to determine the amount of gas needed to fill the tank.

    0.2             0.8

  =    

288.75             x

                                                              231 gal

so, 0.2x = (0.8)(288.75 gal), and x = = 1155 gal.

                                                                0.2

it would take 1155 gal. to fill the tank.

the cost would be

1155 gal         $3

* = $3465   (answer)

      1           1 gal

hope this you

answer: f = 32.2m

step-by-step explanation: that is the answer

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.

its 60

4 x 12 = 48

3 x 4 = 12

48 + 12 = 60

yeeeet
