What expression is equivalent to -5x^(2)-10x

Good morning ☕️

-5x(x + 2)

Step-by-step explanation:

the key is factoring:

-5x² - 10x = -5x × (x) - 5x × (2)  {here we notice that -5x is a common factor}

               = -5x(x + 2)

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

answer: sine
