Answer:4 2/3
Step-by-step explanation:
5a-5=7+2+2a (combine like terms; 7+2=9)
5a-5=9+2a (subract 2a from both sides; 5a-2a=3a)
3a-5=9 (add 5 to both sides; 9+5=14, -5+5=0)
3a=14 (divide both sides by 3; 14/3= 4 2/3)
Answer: Yes, this is correct!

Are you in k12 online school geometry? If so, good luck! It gets better and easier in Algebra 2 lol
Answer:
The graph of the rectangle missing in the question is shown in the figure attached.
Coordinates of the points are:
A(1,8)
B(4,5)
C(14,21)
D(17,18)
The area of the rectangle is AB*BD.
The length of a segment given two points (x1, y1) and (x2, y2) is computed as follows:
√[(y2 - y1)^2 + (x2 - x1)^2]
For segment AB:
√[(5 - 8)^2 + (4 - 1)^2] = √18
For segment BD:
√[(18 - 5)^2 + (17- 4)^2] = √338
Then, the area is:
AB*BD = (√18)*(√338) = √(18*338) = √6084 = 78
Answer:
34 units
Step-by-step explanation:
34 units
D = dx2 + dy2 W = (5-10)2 + (10-5)2 W = (5)2 + (5)2 = 7.071 L = (5-12)2 + (10-17)2 L = (7)2 + (7)2 = 9.899 A = 2L+2W = (2)9.899+(2)7.071= 33.94 units
