if B is between C and D, BC= 10 in., and BD=3 in., then CD =2AD
This is simple you just need to think what minus or plus the variable in each equation (letter that represents an unknown number) equals what the equations do

Answer:
x = 6
Step-by-step explanation:
let 'x' = BD
x/3 = 12/x
x² = 36
x = 
x = 6
Answer: 5%
Step-by-step explanation:
Hi to answer this question, first we have to calculate the discount amount:
Original price - sale price
500-475 =25
Now, the original price (500) multiplied by the percent discount in decimal form (x) must be equal to the discount amount (25)
500x =25
Solving for x
x =25/500 =0.05
Multiply it by 100 to express in percentage form.
0.05 x 100 = 5%
Feel free to ask for more if needed or if you did not understand something.
The x-intercept of f(x) = (x + 6)(x - 3)
f(x) = 0 → (x + 6)(x - 3) = 0 → x + 6 =0 or x - 3 =0
x = -6 or x = 3
Therefore the x-intercepts are: (-6; 0) and (3; 0)
Your answer is (-6; 0)
