Answer:

Required additive inverse is -7-5i.

Step-by-step explanation:

Given number is -7+5i.

We know that if complex number is a+bi then it's additive inverse is given by a-bi.

Basically we need to change the sign of imaginary term.

imaginary term in given number -7+5i is +5i.

Changing sign of +5i gives -5i.

Measure the distance from point A to points B, C, and D. Round to the nearest eighth of an inch. Reduce if possible.
Vlad1618 [11]

Answer:

if its on a coordinate plane the formula would be:

√(2x-1x)²+(2y-1y)²

Step-by-step explanation:

so if the coordinates were

A= (-3,2)

B= (4,2)

C= (4,-1)

D= (-3,-1)

for A to B it would be

√(4 - (-3)² + (2-2)²

√(7)² + (0)²

√(7·7) + (0·0)

√49+0

√49

or

7
