Answer:

Step-by-step explanation:
2x * 2x * 2x would get the 8x^3
the -3 * -3 * -3 would get the -27
if you do all the other multiplications -36x^2 and 54 X would result
Answer:
Question 16: 44 inches
Question 18: 10, 24, 26
Step-by-step explanation:
<em><u>Question 16:</u></em>
Pythagoras Theorem: c^2 = a^2 + b^2, where c is the hypotenuse and the longest side.
125^2 = 117^2 + b^2
15,625 = 13,689 + b^2
15,625 - 13689 = b^2
1936 = b^2
√1936 = b
44 = b
<em><u>Question 18: </u></em>
Pythagoras Theorem: c^2 = a^2 + b^2, where c is the hypotenuse and the longest side. You have to try all the possibilities. The ones that match are the lengths.
The answers are 10, 24, 26
c^2 = a^2 + b^2
26^2 = 10^2 + 24^2
676 = 100 + 576
676 = 676
Answer: The correct answer is 24.42
Step-by-step explanation:
Radius, r = 1.2ft
Price = $5.40 per ft^2
Area = πr² = 3.14×1.2² = 4.5216 ft²
Cost = 4.5216×5.40 = $24.42
I hope this helps!
