If a + b = 5 and a - b = 9, what is a^2+b^2?

Mark Brainliest please

Answer : 3²+2²=13.

Step-by-step:

Ok …according to the question

a+b=5–(1)considering it as eqn 1

a-b=9—(2)considering it as eqn 2

Substracting eqn 2 from eqn 1 we get

2b=4

b=4/2

b=2

Now substituting this value of b in eqn 1 we get

a+2=5

So a=5–2

a=3

So a=3and b=2
