You are given a rectangle and are told that the length is 1 cm more than twice the width of the rectangle. The area of the rect. is also given, and is 21 cm^2.
Find the length and width. To do this, represent the length by y and the width by x. Then "1 cm more than twice the width" comes out to y=2x+1 (cm).
Since the area of a rect. is equal to the product of its length and width,
x(2x+1)=21 cm^2. Multiply out x(2x+1). show your work. Next, subtract 21 from both sides. Write your algebraic expression on the left side as a quadratic equation in standard form.
Solve this quadratic equation for x. Recall that x (in cm) will represent the width of the rect., and y=2x+1 (in cm) will repr. the length.
Answer:
25. Yes, it is a function, because none of the x outputs are repeating

Answer:
40
Step-by-step explanation:
There are 98 fliers in total
she posted 2/7 in the first week which is equal to : 98 ÷ 7 × 2 = 28
In second week she posted 3/7 of the remaining fliers which is equal to : 70 ÷ 7 × 3 = 30
She has 40 fliers left that is not posted yet.
