Answer:
3. No errors were made. The problem was worked correctly.
Step-by-step explanation:
2(10x + 3) − x = 44
Distribute
20x +6 -x =44
Combine like terms
19x +6 = 44
Subtract 6 from each side
19x =38
Divide by 19
19x/19 =38/19
x =2
Answer:
the scale factor is the vertical expansion factor.
Step-by-step explanation:
The scale factor of 2 in
g(x) = 2·F(x)
means g(x) is a <em>vertical expansion</em> (not shrink) of F(x) — by a factor of 2.
_____
<em>Additional comment</em>
The equation g(x) could be considered to be ...
g(x) = F(x·√2)
in which case g(x) could be interpreted as a <em>horizontal shrink</em> by a factor of (√2)/2. Squeezing a parabola horizontally has the same effect on its appearance as stretching it vertically.

Define x :
-----------------------------------------
Let the smallest number be x.
The other two numbers will be x + 1 and x + 2.
-----------------------------------------
Construct Equation :
-----------------------------------------
Sum of these numbers is 72
⇒ x + x + 1 + x + 2 = 72
-----------------------------------------
Solve for x :
-----------------------------------------
x + x + 1 + x + 2 = 72
3x + 3 = 72
3x = 69
x = 23
-----------------------------------------
Find the numbers :
-----------------------------------------
1st number = x = 23
2nd number = x + 1 = 23 + 1 = 24
3rd number = x + 2 = 23 + 2 = 25
----------------------------------------------------------------------------------
Answer : The numbers are 23, 24 and 25.
