You look for the same variables with the same powers
y: 16y +8y = 24y
x: 8x - 7x = x
y^2: 2y^2
and sum it all together at the end

Factor x²+x-42
First, think of two numbers such that
- If we multiply them we'll get -42
- If we add them we'll get 1
These numbers are:-
7 and -6
Write them here:-
(x+7)(x-6)
<em>Note:-</em>
We don't have to use the Big X method, since the coefficient of x² is 1.
If it's greater than 1, like 2, then the Big X method comes in handy.
<h3>Good luck.</h3>

You can use this equation to help you: (ab)^2 = a^2 b^2. And also (a^m)^n = a^m*n
So, here it is:
(7ab^3)^2 = 7^2 a^2 b^3*2 = 49a^2b^6
The correct answer is the third one - 49 a^2 b^6.
Answer:
$82.68
Step-by-step explanation:
Original price of mint - $106
Percent discount = 22%
Discount price = 22/100 * 106
Discount price = 0.22 * 106
Discount price = $23.32
New value = Original price - discount price
New value = 106 - 23.32
New value = 82.68
Hence the new value of the figure will be $82.68
