Answer:
regular number; base
Step-by-step explanation:
The distance ( S ) is represented by the equation:
S ( t ) = - 16 t² + 25
- 16 t² + 25 = 0
- 16 t² = - 25 / · ( - 1 )
16 t² = 25
t ² = 25 / 16
t = √( 25/16) = 5/4 = 1.25 s ( we will not accept the negative value )
Answer:
The acorn is moving trough the air for 1.25 seconds.
Answer:
After finding like terms and solving, we get 
Step-by-step explanation:
We need to find like terms and simplify the expression 
Like terms: The terms who have same variable and exponent are called like terms.
So, Combining like terms and solving:

So, after finding like terms and solving, we get 
<u><em>Note: In the question given we have - and + sign with the term 5x</em></u> i.e 4- 2x + x^2 -+ 5x + 12 + 2x^2
I have solved using +5x, but if the term is -5x then the solution will be:

So, the answer will be: 
If n is the first integer, then n+2 is the second one. The equation for the sum can be written as
n + (n+2) = 24 . . . . . . this equation can be used to solve the problem
2n = 22 . . . . . . . . . . . simplify, subtract 2
n = 11
The integers are 11 and 13.
_____
I like to solve problems like this by looking at the average of the integers. Here, it is 24/2 = 12. The consecutive odd integers whose average is 12 are 11 and 13.
To find the original price, add the discount back onto the sales price.
17.55+5.85= 23.4
So your answer would be $23.40. Hope this helps!
