6i = 72

I=72/6

I = 12

How many triangles can be constructed with sides measuring 5 m, 16 m, and 5 m?
Ksivusya [100]

Answer:

Here we are given with the sides of the triangle as 5m, 16m and 5. The sum of the length of the two sides should be greater than the length of the third side. But this inequality fails here. Hence no triangle can be made.

Hope this helped

The sum of the squares of three consecutive<br> numbers is 194. What are these squares?
ZanzabumX [31]
The 3 consecutive integers are

n
n + 1
n + 2

Then

n2 + (n + 1)2 + (n + 2)2 = 194

n2 + (n2 + 2n + 1) + (n2 + 4n + 4) = 194

3n2 + 6n + 5 = 194

3n2 + 6n - 189 = 0

n2 + 2n - 63 = 0

(n - 7)(n + 9) = 0

n = 7 or -9

If n = 7, the 3 integers are 7, 8, and 9
If n = -9, the 3 integers are -9, -8, and -7

PLEASE HELP! Find code (answer)
alexandr1967 [171]

Answer:

code = 56

Step-by-step explanation:

E = GCF(22,30) = 2

F = LCM(3,8) = 24

Given

3 * (7+10) = G +30 => 51 = G + 30 => G = 21

5 * (3+H) = 15 + 45 => 3+H = (60/5)  = 12 => H = 12 - 3 = 9

Sum E + F + G + H = 2 + 24 + 21 + 9 = 56
