Answer:
313.3 mm²
Step-by-step explanation:
A = Al + Ab
= Pb×ap/2 + 43.3mm²
= 30mm×9mm + 43.3mm²
= 270mm² + 43.3mm²
= 313.3 mm²
It is 11m+8

Margaret drove 30 miles one way and 30 miles back, totaling 60 miles.
Given that Margaret drove to a business appointment at 30 mph, and her average speed on the return trip was 20 mph, and the return trip took 1/2 hr longer because of heavy traffic, to determine how far did she travel to the appointment the following calculation must be performed:
- 30 - 20 = 10
- 10 = 0.5 hours = 30 minutes
- 30 = 1
- 20 = 0.666
- 1 = 1
- 1.333 = 1.5
- 1 = 30 x 2 = 60
Therefore, Margaret drove 30 miles one way and 30 miles back, totaling 60 miles.

Answer:
X=12
Step-by-step explanation:
Add the two equations together and equate them to 180 due to the geometrical reason that angles on a straight line add up to 180.
10X-20+6X+8=180 (collect like terms)
10X+6X=180-8+20
16X=192 (Divide both sides by 16)
X=12
