How many of these do u want done?
Assuming that m stands for meter, and those are the side lengths.
We have to multiply them together:
10.6 * 1.2 = 12.72
Thousand is 1000
look at previous digit
8
8>5 so round up
533,000 is rounded
Here you have two terms connected by the "subtraction" symbol.
The two coefficients are 2 and 32, and one factor common to both of these is 2. Thus, <span>2x^2-32y^2 = 2(x^2-16y^2).
You could stop here. But it'd make more sense to continue, since x^2-16y^2 is easy to factor:
The three factors of </span><span>2x^2-32y^2 are 2, x-4 and x+4</span>
Y = 4 - x
3x + 4(4-x) = 14
3x + 16 -4x = 14
-x = -2
x = 2
y = 2
