What are the factors of the expression (y-2)(x+3)?
Answers
(y-2) (x + 3) are factors of the xy + 3y-2x-6 form
Further explanation
Factoring is a statement of a form of addition into a multiplication
There are several factoring of the following forms:
- 1. the forms ax + ay + az and ax + bx -cx
factoring:
ax + ay + az = a (x + y + z + ...)
ax + bx -cx = x (a + b-c)
- 2. difference of two squares x²-y²
factoring:
x²-y² = (x-y) (x + y)
- 3. the form x² + 2xy + y² and x²-2xy + y²
factoring:
x² + 2xy + y² = (x + y) (x + y) = (x + y)²
x²-2xy + y² = (x-y) (x-y) = (x-y)²
- 4. form ax² + bx + c with a = 1
factoring:
ax² + bx + c = (x + m) (x + n) with m x n = c and m + n = b
- 5. the form ax² + bx + c with a ≠1 and a ≠0
factoring:
can be completed in 2 ways
a. distributive way
ax² + bx + c = ax² + px + qx + c with
p x q = a x c and
p + q = b
b. formula way
ax² + bx + c = 1/a (ax + m) (ax + n) with
m x n = a x c and
m + n = b
So from an addition form, for example:
ax + ay = a (x + y), then a and (x + y) are factors of the form ax + ay
So (y-2) (x + 3) are factors of the form xy + 3y-2x-6

The answer to 31,096 + 59,721 is 89,817 so B 89,800 is the best estimate
2nd- The answer to 69,896 - 42,901 is 26,995 so A 26,900 is the best answer
3rd- 630,429 - 27,811 is 602,618 so the best answer(s) would be A 630,400 and C 27,800

This is tricky because it has a lot of variables, but we just have to treat this problem normally.
separate y from p + n (feel free to check that you can do this by multiplying y out again and seeing that we have the same thing as before)
divide p + n on both sides

Answer:
She have to pay the bank at the end of the 6 years = 222000$
Step-by-step explanation:
Formula applied in this case where price, interest rate and time duration is mentioned.
Interest = prt/100
Substituting all the given values in the formula.
interest = 15000 * 6 * 8/100
150 * 6 * 8 = 7200
Interest + 15000 = 15000 + 7200 = 222000$ has to pay the total.
In this question amount is 15000 multiply by 6 and by 8 then divide it by 100 so we get the interest then we add it in to amount so we get an answer that is total amount which he has to pay.
