Answer:
B, C, and E
Step-by-step explanation:
One way to rewrite an expression so it's still equivalent is to factor it. To factor an expression, you need to first find the GCF. The GCF of 5x and -15 is 5. The expression is rewritten as <u><em>5(x-3)</em></u> because 5x÷5 = x and -15÷5 = -3. We see that expression is one option so it is one answer. To solve <u><em>4x + 3y - 15-3y + x</em></u>, combine like terms. 4x + x = 5x, 3y - 3y = 0, and -15 is just -15. The expression becomes 5x - 15, which is the same thing, so it's one of the options. The next expression contains <em>y</em> variables, and the sum doesn't equal 0, so that won't be one of the answers. Lastly, <u><em>-20 - 3x + 5 + 8x = -20 + 5 - 3x + 8x</em></u> = -3x + 8x - 20 + 5=5x - 15, which is the same thing also. The answers are B, C, and E.
Hope this helps and it's not too long! I got it right on Edgen.
