Answer:
D
Step-by-step explanation:
Answer:
3
Step-by-step explanation:
It is 3 because fi you multiply 5 by 3 you get 15, and if you multiply 10 by 3 you get 30. Subtract 30 by 6 and get 24. And finally, if you multiply 2 by 3 it gives you 9. 9+12= 21.
Answer:
12.6 ÷ 2.8 = 4.5
Step-by-step explanation:
I hope this helps.
----------------------------------
Define x :
----------------------------------
Let the width be x.
Width = x
Length = 2x + 5 // Length is 5ft longer than twice the width
----------------------------------
Formula for Perimeter :
----------------------------------
Perimeter = 2 (Length + Width)
----------------------------------
Find Width :
----------------------------------
58 = 2 ( 2x + 5 + x) // Substitute Length and Width into formula
58 = 2 (3x + 5) // Combine like terms
58 = 6x + 10 // Apply distributive property
48 = 6x // Take away 10 from both sides
6x = 48 // Switch sides. Make x the subject
x = 8 // Divide by 6 on both sides
----------------------------------
Find Length and Width :
----------------------------------
Width = x = 8 ft
Length = 2x + 5 = 2(8) + 5 = 21 ft
--------------------------------------------------------------------
Answer: The length is 21 ft and the width is 8 ft.

1st part: you do 180 - 110 = 70
Why you subtract 180 from 110 is linear adds up to 180, so 70 + 110 would get 180 if that makes sense.
2nd part: 180 - 115 = 65
This is similar concept to what I explained with the first part.
3rd part: Triangle sum theorem is 180
4th part: To get angle 7 I believe you just subtract
180 - 70 - 65 = 45
5th part: 7 and 6 I believe are vertical angles and vertical angles are congruent which would make 6 = 7
6 would also = 45
Although I cannot see the options for each of the question(s) choices, I hope this can help you. :)
