Find the value of x

-2/15

Step-by-step explanation:

14x+x+15=13

x = -8

Step-by-step explanation:

based on the picture the top line is equal to 13.

So, 14 + x+ x + 15 = 13

      2x + 29 = 13

      2x = -16

x = -8

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
