Answer: the fourth choice: <span>No, the addition symbol was dropped in the second expression
Justification:
1) The right operation is: </span><span>(4.5m + 7/8) - 9 </span><span>= 4.5m + (7/8 - 9), this is you have to keep the + operator, since you are just grouping the terms in an alternate form.
2) Droping the + operator leads incorrectly to the multiplication of the first term, 4.5m to the terms in parenthesis, instead to the addition, which is what corresponds.

To find out how many seconds it would take for him to reach the ground, one would simply have to divide the distance by the rate at which the skydiver is travelling per second.
We know that the skydiver is travelling 1200 feet for ever 5 seconds. To find how many feet he is travelling per second, we simply need to divide the distance by the time.
1200 / 5 = 240
He is falling 240 feet per second.
Now, to find out how many seconds it will take him to reach the ground, we just need to divide that rate into the distance.
10000 / 240 = 41 2/3
It will take the skydiver 41 2/3 seconds to reach the ground.
Hope this helped =)
Answer:
(x-2)(x+5)
Step-by-step explanation:
when factoring, our equation should be in this format: (x+__) (x+__) Then we have to find numbers that add up to 3 but multiply to -10 aka -2 and 5. -2+5=3 and -2(5)= -10
Answer:
The equation of a circle having the center (a, b) and radius r could be formulated by:
(x - a)^2 + (y - b)^2 = r^2
A circle, which has equation form: (x + 3) ^ 2 + y ^ 2 = 81, can be turned into:
(x - -3)^2 + (y - 0)^2 = 9^2
=> center (-3, 0)
=> radius = 9
=> Option 1 is correct
=> Option 4 is correct
=> Option 7 is correct
Hope this helps!
