area = 1/2 * 15 * 12

area = 90 cm²

Perimeter = add up all sides (AB + AC + BC)

BC = 13 cm

Perimeter = 25cm + 15 cm + 13 cm

Perimeter = 53 cm

m is slope, b is y-intercept , x and y are the points like (0, 3.4)

You said it's the y-intercept but it's not. it's just a point on the graph

Alisiya [41]

s -> no: of standard CD players sold

p -> no: of portable CD players sold.

Profit Per Standard CD player=72$

Profit per Portable CD player =90$

Target Amount =360$

In short: The combined sales of Both the CD player's must exceed or atleast become equal to 360$ to acquire the target.

Thus; the inequality can be stated as:

 72(s) + 90(p) ≥360

-> 36(s) + 45(p) ≥180

-> 12(s) +15(p) ≥ 90

 _______________

->| 4(s) + 5(p) ≥ 30 |
