Answer:
Below.
Step-by-step explanation:
a. (x - √5)(x + √5)
= x(x + √5) - √5(x + √5)
= x^2 + √5x - √5x - 5
= x^2 - 5.
b. 10 - 3x^2
= (√10 - √3x) (√10 + √3x)
Answer:
B
Step-by-step explanation:
Mean means average. So if you have a bunch of people around 18 years old, then your average will be 18. Hope this helps!
Answer: C. an investment plan that guarantees payments at regular intervals after retirement
Step-by-step explanation:
- The definition of an annuity is a sum of money or an investment that is paid at regular intervals after retirement.
Annuities are formed and sold by financial institutions, which accept and invest funds from persons and then, upon annuitization, issue a sequence of payments at a later point in time (mostly after retirement).
The area of the classroom is 8,671 in squared. you get this by multiplying base x height x width. You plug the same formula into the dollars he mentions and get 0.06890922 in squared. Than you divide the classroom dimensions by the dollar dimentions. that's 8,671 ÷ 0.06890922 = 125,832.21809795. rounding that to one decimal place, it would take $125,832.2 to fill up the classroom. (I might have gotten this wrong but I think this is the answer)
