Answer:
483 ft²
Step-by-step explanation:
2(7x7)= 98
3(5x12)=180
2(12x5)=120
2(5x5)= 50
1(7x5) = <u> 35 </u>
483
I honestly don't know, but I think it is 63
Answer: y= -5x+4
Step-by-step explanation:
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: D
i would go with D i am not 100% sure math is not my strongest point
