The equation made from this is:
Let x = each 500 grams

Cooking time = 30x + 20

2.5 kg = 2500 grams
2500 / 5 = 5
X = 5

We put this in to the equation,
30*5 + 20 = 170 minutes

It will take 170 minutes to cook a joint of meat weighing 2.5 kilograms

Answer:

15i and 4i

Step-by-step explanation:

i is an imaginary number also shown as $\sqrt{-1}$ .

Since we have $\sqrt{-15}$ , thats 15* $\sqrt{-1}$ . Substitute $\sqrt{-1}$ for i and we get 15*i or 15i.

We do the same for $\sqrt{-4}$ . This is 4* $\sqrt{-1}$ or 4*i or 4i.

An easy way to do this is to take the negative inside the square root like $\sqrt{-6}$ , take the absolute value -6 absolute value=6 and times it by i. So now it becomes 6i
