X=58 the exterior angle is “D” 60degrees
Answer:
12a+2b
Step-by-step explanation:
1. Expand by distributing terms.
20a-8b-2(4a-5b)20a−8b−2(4a−5b)
2. Expand by distributing terms.
20a-8b-(8a-10b)20a−8b−(8a−10b)
3. Remove parentheses.
20a-8b-8a+10b20a−8b−8a+10b
4.Collect like terms.
(20a-8a)+(-8b+10b)(20a−8a)+(−8b+10b)
5. Simplify.
12a+2b12a+2b
6.Answer
12a+2b
Answer:
4.5 meters
Step-by-step explanation:
The formula for the area of a rectangle is length x width. Using this formula, you can substitute the given information and find the area:
length x width = area
0.3km x 0.15km = area
0.045km = area
Finally, you can now convert square kilometres into square meters by multiplying by 100:
0.045 x 100 = 4.5 meters
