$xy - 5y - 2x + 10 \\ y(x - 5) - 2(x - 5) \\ (x - 5)(y - 2)$

So, F(X) = ( X - 5 ) ( Y - 2 )

When you wanna factor out some equation, try to spot things that are similar. Factoring is always a process of trial and error, but as you get more experience it will just get easier.

For example, in your question when you see y appear in many terms try to factor it out, and then produce what goes inside parenthesis.

Alex73 [517]

Answer:

2550yards

Step-by-step explanation:

Perimeter of a rectangle = 2L + 2W

L is the length

W is the width

If perimeter of a rectangle is 425 yards, then;

425 = 2L + 2W

425 = 2(L+W)

L+W = 425/2 .... 1

If the length and width of the rectangle are each multiplied by 6

P = 6(2L) + 2(2W)

P = 12L + 12W

P = 12(L+W) .... 2

Substitute 1 into 2

P = 12(425/2)

P = 6*425

P = 2550yd

Hence the perimeter of new triangle is 2550yards

Solve x (give answer as fractions or integers). 2^x =1/2

Rudik [331]

Answer:

x = -1

Step-by-step explanation:

When an exponent is negative, you have to move it to the denominator (or to the numerator if it's already on the denominator). Since the answer is $\frac{1}{2}$ , you know that the 2 has been raised to the power of 1 (any number to the power of 1 is the same number), so you just make it negative. Hope that helps!
