Answer:
a^2 + 2a + 2
Step-by-step explanation:
replace x with (a +1) everywhere in the equation
f(a+1) = (a+1)^2 + 1
➡
a^2 + 2a + 1 + 1

Find the unit rate of this scenario. 250/2 = 125 quarts per hour
Now multiply the unit rate by the new amount. 36*125 = 4500
Add the units
4,500 quarts in 36 hours.
Step-by-step explanation:
= 2x - 9y + 4x + 11y
First of all combining like terms
So
= 2x + 4x - 9y + 11y
= 6x + 2y
Now putting values
= 6 (-2) + 2(4)
= - 12 + 8
= - 4

Answer:
- 3n+6 (n = smallest)
- 3n (n = middle)
Step-by-step explanation:
The usual method for doing this is to let n represent the smallest one. Then the three integers are ...
n, n+2, and n+4
and their sum is ...
(n) +(n+2) +(n+4) = 3n+6 . . . . sum of 3 consecutive odd integers (n = smallest)
_____
Personally, for consecutive number problems, I prefer to let the variable represent the average value. If n is the average value of 3 consecutive odd integers, is is the middle integer. Of course, the sum will be 3 times the average:
(n-2) +(n) +(n+2) = 3n . . . . sum of 3 consecutive odd integers (n = middle one)
