How many is (-5-3+1)➗(-2+2)

undefined

How many is (-5-3+1) : (-2+2)

(-5-3+1) : (-2+2)

= (-7) : (0)

= (-7) : 0

= undefined

The answer of (-5-3+1) : (-2+2) is undefined

Error

Step-by-step explanation:

To solve an equation, we must look at PEMDAS:

Parenthesis, Exponent, Multiplication, Division, Addition, Subtraction.

This is the order we solve equations in. If you do it any other way, you might get a wrong answer.

Let's look at the problem. We see there are two parenthesis; the PEMDAS states to start with PARENTHESIS first.

Let's solve each one.

(-5-3+1)=-5+-3+1=-7

(-2+2)=0

Plug it back into the equation: 7/0

We cannot divide by zero, so the answer is error.

1. is 4 and 2. is 3

step-by-step explanation:

so if you look at the first one you see that 1 is to 4 and 2 is to 8 and so on, so you can see for every 1 there is a times 4 so if it were 3 then it would be 3*4 and it is 12

for number 2 it is 3 because 1 is to 3 and 2 is to 6 so for every 1 there is 3 so if it were 3 then there would be 3*3 = 9

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
