Multiplying positive numbers always comes out positive, no matter how many there are. So you can forget about the positive ones.
Every two negative numbers in a multiplication produce a positive.
Another way to say that is: If the number of negative ones is EVEN,
the answer is positive, and if it's ODD, the answer is negative.
That monster product of eight numbers in problem #12 will be negative,
because there are an odd amount of negative factors in it.
Convert 3 yards to inches.
1 yard = 36 inches
3 * 36 = 108
Now subtract this from Jason's jump:
108 - 98 = 10
So Doug's jump was 10 inches longer than Jason's jump.
Answer:
5i
Step-by-step explanation:
-25 can be written as 25 x -1
so root -25 is equal to root 25 x -1
root -1 can also be written as i
so root -25 is root 25 multiplied by i
simplifiying this to 5i
Answer:
a=15.21 ft^2
Step-by-step explanation:
a=pi(r)^2
d=2r
A=1/4pi(d)^2=1/4pi(4.4)^2=15.20531ft^2
