Answer:
Step-by-step explanation:
n + n+1 + n+2= 189
3n+3=189 now subtract the three from each side
3n = 186 now divide by three on each side
n = 62
Answer:
Surface Area = inches²
<u><em>OR</em></u>
Surface Area ≈ 24.4 inches²
Step-by-step explanation:
Surface Area =
Where a = 2 inches and h = 5 inches
Surface Area =
Surface Area =
Surface Area = inches²
<u><em>OR</em></u>
Surface Area ≈ 24.4 inches²
7 because 7 x 7 is 49 but if you add 7 and 7 it gets to 14 7 is the answer
so if you do a different number you will be wrong
13Y≤-12

Your question isn't clear. But I infer this is the clear rendering of it;
How many diagonals does a polygon have with 5 sides, but with 6 sides?
Answer:
a. For 5 sides= 5
b. For 6 sides= 9
Step-by-step explanation:
Remember, this is the formula to calculate the number of diagonals of a polygon;
n (n-3) / 2 where n is the sides.
Thus,
for 5 sides= 5 (5-3) /2
= 5 (2) /2 = 10/2= 5
for 6 sides= 6 (6-3) /2
= 6 (3) /2 = 18/2= 9
