-3x+9 = -3(2x+3) + 3(x-4)+1
distribute
-3x+9 =-6x-9+3x-12+1
add like terms
-3x+9= -3x-20
add 3x to each side
9 = -20
there are no solutions because 9 does not equal -20
Area of a circle is found using the formula: A = PI x r^2 where r is the radius of the circle, which is half the diameter.
Using the information in the problem you have:
A= PI x 15^2
A = PI x 225
A = 706.5 sq. In.
-5n + 8 = -7
-5n + 8 - 8 = -7 -8
-5n = -15
-5n/-5 = -15/-5
n = 3
You are comparing velocities. Without a given acceleration, the time can not be found.
Answer:
the last one
Step-by-step explanation:
its the last one because 1x3 is 3 so you need one with a 3, then 4x2 is 8 and theres half a side so its the last answer with half 3/4 on one side
