Answer:
13 cm, 39 cm, 39 cm
Step-by-step explanation:
If x is the short side, then the other two sides are 3x and 3x. The perimeter is the sum of side lengths:
x +3x +3x = 91
x = 91/7 = 13
3x = 3(13) = 39
The length of the short side is 13 cm; the other two sides are 39 cm.
32% means 32/100
32/100 = 16/50 = 8/25, which is the lowest you can get because you can no longer divide it to get a whole number.
A; 8/25.
Answer:
78
Step-by-step explanation:
10% = 6
⬇️ x3
30% = 18
⬇️ Add onto 60
60+18=78
(1/2)^2 = 1/4
2-2/3 = 6/3 - 2/3 = 4/3
OK so:
(1/2)^2 - 6(2-2/3) = 1/4 - 6(4/3)
= 1/4 - 8
= 1/4 - 32/4
= -31/4
Multiply 3x by -6, it gives you -18 so I'm going to say D
