Answer:
i = 2
Step-by-step explanation:
First move -2i to the other side of the equation like this: 4 = 2i
Then divide both sides by 2: 4/2 = 2i/2
Then you get your answer!: i = 2
Answer:
GH = 17 units
GI = 39 units
HI = 39 units
Step-by-step explanation:
We are given the following information in the question:
Triangle GHI is an isosceles triangle.

The measures of side are:

It is given that
GI = HI

Thus, the measures of three sides are:

5 ft because 3 squared is 9 and 4 squared is 16 9+16=25 25 squared is 5
Answer:
n + n+2 + m+4 = 87
I got this answer.....hope it may helpful
Sum = n/2[2a + (n - 1)d] where a = first term, n = number of terms and d = common difference
(a) 30/2(2 x 5 + (30 - 1) x d) = 1455
10 + 29d = 1455 / 15
29d = 97 - 10
d = 87 / 29 = 3
(b) 7/2(2 x 9 + (7 - 1)d) = 0
18 + 6d = 0
6d = -18
d = -3
