Y = (x - 5)²
y = (x - 5)(x - 5)
y = (x² - 5x - 5x +25)
y = x² -10x + 25
Answer: 31.416
Step-by-step explanation: Multiply the diameter by pi OR you could divide the diameter by 2 and then use the formula 2(pi)(radius).
The areas of the square pyramid are the amount of space on it
- The lateral surface area is 292.5 square cm
- The total surface area is 354.85 square cm
<h3>How to determine the lateral surface area?</h3>
The given parameters are:
Base (b) = 15 cm
Slant height (l) = 13 cm
The lateral surface area is calculated using:
L = 1.5bl
So, we have:
L = 1.5 * 15 * 13
Evaluate the product
L = 292.5
<h3>How to determine the total surface area?</h3>
This is calculated using:
T = L + 0.25√3b^2
So, we have:
T = 292.5 + 0.25√3 * 12^2
Evaluate
T = 354.85
Hence, the total surface area is 354.85 square cm

Answer:
1 + 2 + 3 + 4 + 5 + 9=24
10 + 9 + 8 + 2 + 1 + 6=36
Step-by-step explanation:
When you mean you can only use the numbers once do you mean you can't use it twice on the same one or you can't use the number after you have used it on one of them?
