12. A garage is x metres wide. It is 5 metres longer than it is wide. The area of the garage floor is 24m? Using this information, write a quadratic equation for the area of the floor.
Draw a graph of the equation in the domain --8 (1) What is significant about the two values x = -8 and x = 3, on the curve?
(ii) What is the only valid value of x? Explain your answer.

How many solutions does the nonlinear system of equations graphed below have?

Consider a bag that contains 220 coins of which 6 are rare indian pennies. for the given pair of events a and b, complete parts (a) and (b) below. a: when one of the 220 coins is randomly selected, it is one of the 6 indian pennies. b: when another one of the 220 coins is randomly selected (with replacement), it is also one of the 6 indian pennies. a. determine whether events a and b are independent or dependent. b. find p(a and b), the probability that events a and b both occur.

Ineed to know the ordered pairs for this equation i need the answer quick because it’s a timed test
