To factor this quadratic equation into double brackets, you need to find two numbers that add together to equal 10, but also multiply to give you 9. These two numbers can be identified as 1 and 9, which will be the numbers you place in your parentheses as follows:
(x+1)(x+9)
Answer:
y = 3/4x - 8/3
Step-by-step explanation:
y = 3/4x + b

1/3 = 3 + b
-8/3 = b
y = 3/4x - 8/3

Step-by-step explanation:
To find the missing side of a right triangle, use the Pythagorean Theorem. The Pythagorean Theorem is 
where a and b are the legs with a being the smallest and c is the hypotenuse.
1. a=6, b=8, c=?
2. a=5, b=?, c=13
3. a=7, b=9, c=?
4. a=2, b=?, c=7
