Perimeter- 14x+6
Just add al the sides up like normal
Area- 12x^2+9x
Multiply the length and width
C)
Perimeter- 118
Area- 840
I’m pretty sure these are right
Let X describes the sales
350.25+0.12x=800.5
Now solve for x
0.12x=800.5-350.25
0.12x=450.25
X=450.25÷0.12
X=3,752.08
the sales necessary for the salesperson to earn at least $800.50 in one week is 3,752.08
Count the number of cubes shaded so the 7x11 is 77 square units
hope that this helped you hon :)
