Andrew has a different cookie recipe that makes 28 cookies. He plans to have 21 guests at the party and wants each guest to have

joja [24]

Answer: Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies.

Step-by-step explanation: Since each recipe makes 28 cookies, tripling the recipe would give him 28(3) = 84 cookies.

Then divide the total number of cookies by the number of guests: 84 21 = 4. Each person would get 4 cookies.

This process can be modeled by the expressions 28(3) ÷ 21 and

28(3)

21

. This is because the fraction bar represents division.

NEED HELP PLEASE!

USPshnik [31]

Answer:

$(x + (3+5i))^2 = x^2 + 6x + (10x+30)i - 16$

Step-by-step explanation:

Complex numbers identity:

The complex numbers identity is:

$i^2 = -1$

Square of the sum:

$(x + y)^2 = x^2 + 2xy + y^2$

In this question:

$(x + (3+5i))^2$

$x^2 + 2x(3+5i) + (3+5i)^2$

$x^2 + 6x + 10xi + 9 + 30i + 25i^2$

$x^2 + 6x + 9 + (10x+30)i - 25$

$x^2 + 6x + (10x+30)i - 16$

$(x + (3+5i))^2 = x^2 + 6x + (10x+30)i - 16$
