The cooking instructions for roast chicken state that it needs 90 minutes plus an additional 15
minutes per kilogram. As a formula, this is written:
T = 90 + 15m
where T is the time, in minutes, and m is the mass, in kilo-
grams.
Juan calculated the cooking time for a chicken as 2 hours 45
minutes.
a How heavy was Juan's chicken?

5 kg

Step-by-step explanation:

165 = 90 + 15m

75 = 15m

m = 75/15

m = 5

answer: 1) twenty-seven times y

              2) twenty-seven multiplied by y

just take the area of the square and then the area of the circle then subtract the circle area from the squares area
