Question

I submitted y=13 I wouldn't work so what can it be?

Answer 1

b) y = + 13

Explanation:

Now we have to,

→ find the required value of y.

The problem is,

→ y² = 169

Let's solve the problem,

→ y² = 169

→ y = √(169)

→ [ y = + 13 ]

Hence, the answer is + 13.

Answer 2

`\huge\boxed{\sf y = \pm 13}`

Explanation:

Given that,

y² = 169

Take sq. root on both sides

√y² = √169

y = ±13

So,

y = 13 OR y = -13

`\rule[225]{225}{2}`
