There are four terms in your algebraic expression.  Notice that the left two terms have the factors 2 and x in common, whereas the right two terms have the factors 3 and y in common:

2x(x-5y) + 3y(x-5y).  Can you now factor this further?  Note that the two terms here have a common factor, (x-5y).

Please help with my algebra homework and explain if you can
balandron [24]

A= \frac{1}{2} h (x+y)

we have to solve for x , solving for x means , we have to isolate x one one side , by shifting all other variables to other side

So

A= \frac{1}{2} h (x+y)

Multiply both sides by 2

2A = h(x+y)

Divide both sides by h

2A/h = x+y

Subtract y from both sides

\frac{2A}{h}  -y =x

or

x=\frac{2A}{h}  -y

Find the domain, range and if it’s a function.
Marta_Voda [28]
Domain: {-1}
Range: {0, 4, 9, 15}
Function? No

Explanation:
The domain is the x value in the given points. The only x value is -1.
The range is the y value in the given points.
You can tell if this is a function if it has repeating x values or not. Since the x value of -1 repeats, it is not a function.

Hope this helps, and please mark brainliest :)
