Step-by-step explanation:
AC = AB + BC
25x - 19 = 9x + 7 + 5x + 7
25x - 19 = 14x + 14
25x - 14x = 14 + 19
11x = 33
x = 33/11
x = 3
AB = 9x + 7
= 9(3) + 7
= 27 + 7
= 34
Answer:
4pi
Step-by-step explanation:
area of a circle is pi*r^2
and you have diameter of 4
so 4/2 gives radius which is 2
A = pi*2^2 = 4pi
Y2-y1/x2-x1 is slope so
9-9/14-(-20) so you get 0/34 which means there is no slope since they have the same y (the equation would be y=0x+9 therefore y=9)
Which makes sense since the equation is a straight line
Answer:
21.333 miles per gallon
Step-by-step explanation:
Radius = 24.49
