Answer:

a) $\\ \\ \\2x + y \\ 2(4) + (3) \\ 8 + 3 \\ \sf\green{\boxed{11}}$

b) $\\ \\ \\{a}^{2} + b \\ { - 2}^{2} + 5 \\ 4 + 5 \\ \sf\green{\boxed{9}}$

Answer 2

Qᴜᴇsᴛɪᴏɴ 1 :

• x = 4
• y = 3

Fɪɴᴅ :

• 2x + y

Sᴏʟᴜᴛɪᴏɴ :

➪ 2 ༝ 4 + 3

➪ 8 + 3

➪ 11

• Hence, the value is 11.

Qᴜᴇsᴛɪᴏɴ 2 :

• a = - 2
• b = 5

Fɪɴᴅ :

• a² + b

Sᴏʟᴜᴛɪᴏɴ :

➪ ( - 2 )² + 5

➪ 4 + 5

➪ 9

• Hence, the value is 9.
