Rewrite the equation by completing the square. x^2+10x+24 = 0
ser-zykov [4K]

Answer:

(x+5)^2 = 1

Step-by-step explanation:

x^2+10x+24 = 0

Subtract 24 from each side

x^2+10x+24 -24 = 0-24

x^2+10x = -24

Take the coefficient of x

10

Divide by 2

10/2 =5

Square it

5^2 = 25

Add it to each side

x^2+10x+25 = -24+25

Take the coefficient divided by 2 inside the factor

(x+10/2) ^2 = -24+25

(x+5)^2 = 1

four balls of wool will make 8 knitted caps.how many balls of wool will malcom need if he wants to make 6 caps?
miss Akunina [59]
We can express this as a ratio. 4 balls :8 caps.

Then simplify. 1 ball: 2 caps.

We have to make caps equal to 6, so multiply by 3. For consistency, we need to multiply the number of balls by 3 too.

3 balls: 6 caps.

So Malcolm needs 3 balls of wool.
