x^2 + xy - 2x - 2y
= x(x + y) - 2(x + y)
= (x - 2(x + y)
Answer:
No, because using the distributive property, you would get 5b+15 and 3b+15. The number of b you have is different.

<span>The sum of 324, 435, and 546 is 1305. If this number were to be expressed by the base of 7, we would need to figure out what value of exponent would satisfy the requirement. This can be done by setting up an equation where 7 to the power of x must equal 1305. Using logarithms, one can solve for x and find it to be 3.6866853. Thus the sum of the aforementioned numbers, expressed in by the base of 7, is 7^3.6866853.</span>
