Answer:
Step-by-step explanation:
Length (L)= 2x - 3 cm
Breadth (b) = x + 7 cm
Area of the rectangle
= L * b
= ( 2x - 3)(x+ 7)
= 2x(x + 7) - 3(x + 7)
= 2x² + 14x - 3x - 21
=( 2x² + 11x - 21) cm²
hope it helps

Answer:
21 = .75x - .1x + 3
Step-by-step explanation:
Daria made a profit of $21.00 selling lemonade. She sold her lemonade for $0.75 per cup, received a tip of $3 from a neighbor, but also had to buy each plastic cup she used for $0.10 per cup. Write an equation to represent this situation.
Total Profit = $21.00
x= number of cups
Price of each cup = $0.75
She paid $0.10 for cups used by her
Tip from neighbor= $3
Equation:
Expected Total cost of cups = 0.75 * x
= 0.75x
Cost of cups used = 0.10 * x
= 0.1x
Daria used 0.1x of the total cups that should be sold
Total sold= Expected cups to be sold - used cups
= 0.75x - 0.1x
Profit = Total sold + tip from neighbor
21.00 = 0.75x - 0.1x + 3
21 = .75x - .1x + 3 is the equation
