Answer 2

Answer:

$\boxed{\sf B)\:7}$

Step-by-step explanation:

$\sf 3(x+y)^2-5$

→ $\sf x=4$

→ $\sf y=-2$

_________________________

*Substitute y with -2 and x with 4*

$\sf 3\left(4-2\right)^2-5$

$\blacksquare$ Subtract 2 from 4 = 2

• $3\times 2^2-5$

$\blacksquare$ Calculate 2 to the power of 2 = 4

• $3 \times 4-5$

$\blacksquare$ Multiply 3 and 4 = 12

• $\sf 12-5$

$\blacksquare$ Subtract 5 from 12 = 7

• $\sf 7$
