Answer:
у = x² + 7x - 30
Step-by-step explanation:
x₁ = 3 and x₂ = -10
Use the formula (x - x₁)(x - x₂) = 0
(x - 3)(x - (-10)) = 0
(x - 3)(x + 10) = 0
x² + 10x - 3x - 30 = 0
x² + 7x - 30 = 0
It depends what type of shape it is if it were a rectangle it would be l x w x h but what a see is a 6 sided figure so it should be a hexagon but a hexagon has all equal sides so it would depend what type of shape it is
Answer:
Your answer should be $29.40

4.2 x 7 = 29.4
Therefore, your total cost for 7 books will be $29.40
