X^2=12x-27 solve by factoring

X=3 or X=9

Step-by-step explanation:

Step 1: Subtract 12x-27 from both sides.

x2−(12x−27)=12x−27−(12x−27)

x2−12x+27=0

2: Factor left side of equation.

(x−3)(x−9)=0

Step 3: Set factors equal to 0.

x−3=0 or x−9=0

x=3 or x=9

answer

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
