Ju chan solved the previous question by finding the expression 4(-15).

which addition problem would give the same result? choose all that apply.
15 + 15 + 15 + 15
4 + 4 + 4 + 4
(–1)(15 + 15 + 15 + 15)
(–15) + (–15) + (–15) + (–15)

(-1)(15+15+15+15)

(-15)+(-15)+(-15)+(-15)

Step-by-step explanation:

1. The multiplication shown in the problem above is:

4(-15)

The product is -60

4(-15)=-60

2. The multiplication above could indicate that:

- The number -15 is added 4 times.

- The number 15 is added 4 times and then is multiplied by -1.

- The number -4 is added 15 times.

- The number 4 is added 15 times and then is multiplied by -1.

 Keeping these on mind, you can conclude that the correct options are the third option and the last option:

(-1)(15+15+15+15)=(-1)(60)=-60

(-15)+(-15)+(-15)+(-15)=-15-15-15-15=-60

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*
