Question

(ii) find the value of ab'
and a-b=2 2
when a +b = 5.2​

Answer 1

Answer:

22 sqare

Step-by-step explanation:

Answer 2

Answer:

a+b=5.2.........1

a-b=22

a=22+b..........2

Putting the value of a in equation 1

a+b=5.2

22+b+b=5.2

22+2b=5.2

2b=5.2-22

2b=-16.8

b=-16.8/2

b=-8.4

Now putting the value of b in equation 2

a=22+b

a=22+(-8.4)

a=22 - 8.4

a=13.6

Now we have the values of a & b

ab=13.6X(-8.4)

ab= - 114.24
