17) replace the given number for "x" and evaluate
a) x² + 2x + 1 ; when x = 3
3² + 2(3) + 1
= 9 + 6 + 1
= 16
b) x² + 2x + 1 ; when x = -4
(-4)² + 2(-4) + 1
= 16 - 8 + 1
= 9
c) x² + 2x + 1 ; when x = 3
(-22.872)² + 2(-22.872) + 1
= 523.128384 - 45.744 + 1
= 478.384384
18) The dependent variable is affected by the other variable and is the "output" The independent variable is the input.
a) y = 3x - 5; "x" is the independent variable
b) the time of day is the independent variable (you would input the time of day to calculate the temperature).
19) Let the x-axis represent the length of the lumber cut off and the y-axis represent the length of the lumber remaining.

Answer:
104, 106
Step-by-step explanation:
Hello!
A consecutive number is a number that comes after the other.
Let the first even integer be x. Since there is an even integer for every two integers, the second number should be x + 2.
<h3>Solve for x</h3>
- (x) + (x + 2) = 210
- x + x + 2 = 210
- 2x + 2 = 210
- 2x = 208
- x = 104
The second number is x + 2, so it would be 106.
