For number 1, you start at zero and go to the left since the four is negative four spaces. Then, you go to the right two spaces since the 2 is positive. Your answer is -2
For number 2, you start at zero and go left four spaces since it is negative and then go two more spaces to the left because it is negative again
The answer is 94%. This is a confirmed answer, I took the quiz.
Hope this helps :)
Answer: Um... stuck on the same question dont know
Step-by-step explanation: grump!
Answer:
Factoring
Step-by-step explanation:
x^2 + 7x = x(x + 7) = 0
So
x = 0 or x = -7
So first you have to do PEMDAS (Parenthesis, Exponent, Multiply, Divide, Add, Subtract). Now, when you do PEMDAS, you need to go from left to right in the order I just described to you.
So in this situation, first multiply 5 times 3 to get 15. Next is addition. 15+4=19.
PS sorry for taking so long.
