Answer:

54°

Step-by-step explanation:

We see that 54° and u are corresponding angles of parallel lines. With parallel lines, corresponding angles are congruent, hence, u = 54°.

. Tommy gives baseball cards to four of his friends. He gives Kiana 3 cards less than he gives Gary.

We need to write system of equations for this problem. Reading text we write 1 equation by 1.
first lets name our variables
x - Kiana cards
y - Gary cards
z - Monty cards
m - Willa cards

x = y-3 which we can write as y = x+3
z = x + 7
m = 2z
x + y + z + m = 74

I think easiest way to solve this is to express all variables in last equation and solve for x.
x + x+3 + x + 7+ 2x + 14= 74
5x = 50
x = 10
now we just calculate cards given to each friend

y = 13
z = 17
m = 34

use the function to answer the question. f(x)= x^3 + 5x^2 + 7x + 3 = (x+1)(x+1)(x+3) what is the multiplicity of the root -1? I

Since $f(x)=(x+1)^2(x+3)$ it follows that $x=-1$ is a root of multiplicity 2.
