Answer:

171

Step-by-step explanation:

When you say "the 2 is small" I think you mean it's an exponent so the equation would look like....

9(k+12) + 4k^{2}

if k=3 we would replace all the k's with 3.

9(3+12) + 4(3)²

9(15) + 4(9)

135 + 36

171

So the answer would be 171

Hope that helps and have a great day!

Find the product.
RUDIKE [14]

Answer:

C.  3x2 − 3x − 60

Step-by-step explanation:

3(x + 4) (x - 5) = (3x+12) (x-5)

(3x+12) (x-5) = 3x2+12x-15x-60

3x2+12x-15x-60 = 3x2 − 3x − 60

9. What is the coefficient of y^2? in the expansion of (x + y)^2??
klemol [59]

Answer:

The coefficient of y² will be 1, which we can see when we expand the expression:

(x + y)²

= (x +y)(x + y)

= x² + xy + xy + y²

= x² + 2xy + y²
