Answer:
B.
Step-by-step explanation:
X would be 60, I don’t know an equation, but you can divide both sides by 4 and get 20% of c is 12, and then you can multiply both sides by 5 to get that 100% of x is 60, hope this helps!
Answer:
The correct answer is first option. 204 m²
Step-by-step explanation:
Formula:-
Lateral surface area of square pyramid = 4 * area of triangle
<u>To find the slant height of triangle(l)</u>
l = √(6² + 6²) = 6√2
To find the area of triangle
Area = bh/2
b = 12 m
h = 6√2
Area = (12 * 6√2)/2 = 36√2
<u>To find the lateral surface area of Prism</u>
Lateral surface area of square pyramid = 4 * area of triangle
= 36√2 * 4 = 203.64 ≈ 204 m²
First answer is the correct option
Answer: 280
Step-by-step explanation:
(-11 - 17) (2 - 12) = 280/1 = 280
Subtract: -11 - 17 = -28
Subtract: 2 - 12 = -10
Multiple: the result of step No. 1 * the result of step No. 2 = -28 * (-10) = 280
