Answer:
x = 6
HI = 29
Step-by-step explanation:
✔️HI = ½(AB) => Triangle Mid-segment Theorem
HI = 5x - 1
AB = 58
Plug in the values and solve for x
5x - 1 = ½(58)
5x - 1 = 29
Add 1 to both sides
5x - 1 + 1 = 29 + 1
5x = 30
Divide both sides by 5
5x/5 = 30/5
x = 6
✔️HI = 5x - 1
Plug in the value of x
HI = 5(6) - 1
HI = 30 - 1
HI = 29
Answer:
7.7 ft
Step-by-step explanation:
The third longest side is also the second shortest side.
The 14 ft side of quadrilateral ABCD corresponds to the 6 ft side of quadrilateral EFGH.
14/6 = 18/x
7/3 = 18/x
7x = 18 * 3
7x = 54
x = 54/7
x = 7.7
Answer: D. 7.7 feet
So PEMDAS is order of operations basicly.
P=Parenthesis
E=Exponets
M=Multiplication
D=Division
A=Addition
S=Subtraction
For example: 2x4+(9x9)-1
When solving order of operations you ALWAYS start with the problem in the parentheses.
(9x9)=81
Now multiplication comes next so, 2x4=8
Then addition, 8+81=88
Lastly subtraction, 88-1=81
