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.

Step-by-step explanation:
my dude you need to know this. A=bh. A=10(6).
B)
here,
A to B = 62
C To B = 11
A to C = ?
now,
so, 62 - 11 = 51
therefore a to C Is 51 cm
plz mark me brainliest ok
plz follow me
A)
Here,
A to B = 13
A to C = 26
total = ?
now,
A to B + A to C
13 + 26 = 39
Therefore,
total number is 39
