It's the first one because surface area is l*w of each side and add that all together which is 288 sq in.
Answer:
First answer = 36
Second answer = 9
Third answer =1/4
Step-by-step explanation:
-7x+y=23
6x+7y=-4
y=7x+23
6x+7(7x+23)=-4
6x+49x+161=-4
55x+161-161=-4-161
55x/55=-165/55
x=-3
-7(-3)+y=23
21+y-21=23-21
y=2
1/6
Step-by-step explanation:
- According to the question, the right combination of 2 wires cut (out of the 4 wires ) will defuse the bomb. To find all the possible combinations we using the following formulae;
nCr = n! / r! * (n - r)!
⁴₂C = 4! / 2! * (4-2)!
⁴₂C = 24 / 2 * 2
⁴₂C = 6
- There are a possible 6 combinations
- Therefore for probability of cutting the right combination of 2 wires is 1/6
