Answer:

Your answer is 8

Step-by-step explanation:

Have you heard of PEMDAS?

P = Parenthesis

E = Exponent

M = Multiplication

D = Division

A = Addition

S = Subtraction

You do this in order from left to right. So...

5 + 3squared - 7 + 1         - First you do 3squared

5 + 9 - 7 + 1                       - Now you add 5 and 9

14 - 7 + 1                             - Subtract 14 and 7

7 + 1

= 8

Hope this helps! If so, Brainliest? :)

Answer:

z_1+z_2 = (-2,5)

Step-by-step explanation:

To Find: z_1+z_2

Solution :

Referring the given graph

We can find the coordinates of   z_1 and  z_2

Coordinates of   z_1= (-7,1)

Coordinates of  z_2= (5,4)

Thus Coordinates of  z_1+z_2 = (-7+5,1+4) = (-2,5)

Thus z_1+z_2 = (-2,5)

So, the point z_1+z_2 = (-2,5) is shown on the attached graph file
