Question

2. If x = 15 and y = 20, then x2 + y2 is equal to : (A) 25 (B) 35 (D) 625 (C) (15+20)​

Answer 1

Answer:

option D

625 is the answer of x^2+y^2.

Step-by-step explanation:

if x = 15 and y = 20,

then

${x}^{2} + {y}^{2} = \: \: ?$

${(15)}^{2} + {(20)}^{2}$

$225 + 400$

$625$

Answer 2

Answer:

option D

625 is the answer of x^2+y^2.

Step-by-step explanation:

if x = 15 and y = 20,

then,

${x}^{2} + {y}^{2} = \: \: ?x$

${(15)}^{2} + {(20)}^{2}(15)$

225 + 400

625
