Answer:
A, B and C (close examination)
Step-by-step explanation:
A. 15m3 - 6m = 3m(5m2 - 6m)
B. 40m6-4=4(10m6-1)
- 0 = 0
- All real numbers are solutions
C. 6m2+18m=6m2(1+3m)
D. 32m4+12m3(8m+3)
This is tough one but I will explain this problem by close examination:
The problem is looking for an equation that have the variable m by itself
D is out of the picture because the equations does not have m by itself
Equation B's answer is that all numbers are solutions meaning any m value you put will become the same. (Similar to Infinite Solutions)
By close examination, The answer are A, B, and C.
Answer: It would take 9 hours for 4 painters to paint 720 feet of fence.
Step-by-step explanation:
1.) Calculate the time needed to paint the 720 ft fence with 2 painters.
a.) Divide 720 by 280 to get how many times greater 720 is than 280.
720 / 280 ≈ 2.57
b.) Multiply the time needed to paint the 280 ft fence with 2 painters by 2.57.
7 * 2.57 ≈ 18
2.) Calculate the time needed to paint the 720 ft fence with 4 painters.
a.) Assuming that each painter paints the same amount of fence, divide the time in half, as 4 painters is double the original amount, so it would take half of the time.
18 / 2 = 9
Answer: it’s B
Step-by-step explanation:
Yes because they are at acute angels
2 (d(h+w) + h w) is the surface area
