Perform the indicated operation. 3 + (-4) 1 -1 7 -7

For this case, what we must do is solve the following algebraic expression:

According to the law of signs we have to:

Thus, applying the aforementioned law we have to:

Rewriting we have:

-1

Step-by-step explanation:

3+-4

Since the signs are opposite, we subtract the two numbers and take the sign of the larger

4-3 =1

The sign of the larger number (-4) is negative

-1

3+-4 = -1

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
