Answer:
I disagree with Luis's claim. While 8*3=24, 8^3 is 512mm. Which is 488mm more than 24mm.
201 inches.
Step-by-step explanation:
They use the expression s^3 to find the volume of plastic to make each cube. Luis says that if s=8, then the volume is 24 cubic mm. I disagree with Luis's claim. While 8*3=24, 8^3 is 512mm. Which is 488mm more than 24mm.

Part A
Blue: 3ft - 36in
Red: 60in - 5ft
Yellow: 2.5ft - 30in
Green: 12ft - 144in
Purple: 240in - 20ft
Part B
1 foot = 12 inches
16.75ft = 201in
I'm not sure how to do the expression
but if 1 foot = 12 inches, and you substitute 16.75 for a foot, then you have 201 inches.
Step-by-step explanation:
a) Let y = f(x) = 3x - 2x^2
f(-2) = 3(-2) - 2(-2)^2 = p
= -6 - 8
= -14
= p
f(2.5) = 3(2.5) - 2(2.5)^2 = q
= 7.5 - 12.5
= -5
= q
b) graphing
c) From the graph, you should be able to verify the following:
i) f(0.5) = 3(0.5) - 2(0.5)^2 = 1
ii) 0.5 = 3x - 2x^2 or x = 1.3, 0.2
iii) the maximum occurs at
f(0.75) = 1.125
d) the equation for the line of symmetry is x = 0.75
First you solve the brackets;
68+7 = 75
Then you add the 93;
75+93 = 168
