Answer:

z+7

Step-by-step explanation:

Firstly once you see the word sum it means you will have to add up to get a specific number

For example the sum of 6 and 7 means 6+7 which will give us 13

The sum of z and 7 will z+7,but we observe that z is not a number so we cannot add z+7 but in the case of multiplication that is z×7

It will give us 7z but the case of addition is totally different from that of multiplication

Therefore the final answer is z+7

Answer:

82

Step-by-step explanation:

1'st step: a^{2} + b^{2}= c^{2} is the formula for the pythagorean theorem

3'rd step:   324+6400 =  c^{2}

4'rd step: 6724=  c^{2}

5'th step: \sqrt{6724} =82

6'th step : therefore the value of c is 82 cm
