Answer:
a. 8
b. 61, 23, 84
Step-by-step explanation:
As we can see, point S is between points R and T, therefore:
- RS + ST = RT
- 7y + 5 + 2y + 7 = 14y - 28
- 9y + 12 = 14y - 28
- 14y - 9y = 12 + 28
- 5y = 40
- y = 40/5
- y = 8
------------
- RS = 7y+5 = 61
- ST = 2y + 7= 23
- RT = 14y - 28 = 84

Answer: the answer is 31.5
Step-by-step explanation:
u will need to 9.0 X 3.5 to get the naswer so its 31.5
It's 21 square units. If you map it on a complex plane (x-axis is real numbers, y-axis is imaginary numbers) you'll see that the sides of the rectangle is 3 and 7 which multiply to 21.
