Evaluate the Expression (y+2)2 when y = -4

4

Step-by-step explanation:

(y+2)^2

Let y = -4

(-4+2)^2

Parentheses first

(-2)^2

Exponents

4

-4

Step-by-step explanation:

y = -4

Substituting y in the equation,

(-4+2)2

(-2)2         [Negative x Positive = Negative]

=> -4

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.
