Answer:
4(x+x+1+x+2)=156, x=12
Step-by-step explanation:
let the numbers be x, x+1 and x+2.
Now,
4(x+x+1+x+2)=156
4(3x+3)=156
divide both side by 4
3x+3=156/4=39
subtract 3 from both sides
3x=39-3
3x=36
divide both sides by 3
x=36/3=12
x=12
Hence, the smallest of the integers is 12.
Since the question is asking how many pencils the teacher will have to give out, we can automatically ignore the 46 erasers from the problem because it is not relevant. The information was most likely put there to confuse you.
Each student is getting 28 pencils, so if we multiply the number of students by 28 pencils, we will find how many pencils the teacher will need to give out.
There are 42 children in the classroom, so multiply 42 by 28.
42 * 28 = 1,176
The teacher will have to give out <u>1,176 pencils</u> to her 42 children in the classroom.
Step-by-step explanation:
So first of all we plug in 1 into f(x) and the result of that into g(x).
f(1)=(1)^2-3(1)+5
=1-3+5
=3
g(3)=(3)(22)-2(3)
=66-6
=60
Answer:

Step-by-step explanation:
The domain of a function is all possible values for the value of x.
The denominator in a rational function cannot equal to 0.

Subtracting 2 from both sides.

The domain of the function is all real numbers except -2.
Disagree. Even though it has no b it is still a line but a horizontal line. It will be at 7 on the y- intercept but horizontal.
