The correct answer should be 9 if the perimeter is 12
Answer:
What graph?
Step-by-step explanation:
What graph?
To factor a cube (a^3-b^3) = (a-b)(a^2+ab+b^2)
8 is the cube of 2
r^3 is the cube of r.
So, a is 2 and b is r
(2-r)(2^2+2r+r^2)
(2-r)(4+2r+r^2)
Initially started 20 feet from the ground .
Went uphill 83 feet.
So: 20 + 83 = 103. The coaster is 103 ft above at this point.
Went down 42 feet
So: 103 - 42 = 61.
Went up 128 feet
So: 61 + 128 = 189
Finally, went down 90 feet
So: 189 - 90 = 99
99 ft above ground.
C. $3.00
To find how many bananas you get for a dollar, do 12/2.4 to get 5 bananas per dollar. Since you want to find how much it costs for 15 bananas, you'll do 15/5, which gives you $3
