Answer: 3x^4 - 13x^3 -x^2 - 11x + 6

Step-by-step explanation:

x^2 - 5x + 2 * 3x^2 + 2x + 3

Using the distributive property,

= x^2(3x^2 + 2x + 3) - 5x(3x^2 + 2x + 3) + 2(3x^2 + 2x + 3)

= 3x^4 + 2x^3 + 3x^2 -15x^3 - 10x^2 - 15x + 6x^2 + 4x + 6

= 3x^4 - 13x^3 -x^2 - 11x + 6

T is the midpoint of KL. K has coordinates (2,−6), and T has coordinates (−4,2). Identify the coordinates of L.
kotykmax [81]

Answer:

L = (-10,10)

Step-by-step explanation:

Given

K = (2,-6)

T = (-4,2)

Required

Determine the coordinates of L

Since T is the midpoint of K and L, we make use of:

T_x = \frac{K_x + L_x}{2}

and

T_y = \frac{K_y + L_y}{2}

Solving for L_x

T_x = \frac{K_x + L_x}{2}

-4 = \frac{2 + L_x}{2}

Multiply through by 2

-8 = 2 + L_x

L_x = -8 - 2

L_x = -10

Solving for L_y

T_y = \frac{K_y + L_y}{2}

2 = \frac{-6+L_y}{2}

Multiply through by 2

4 = -6 + L_y

L_y = 4 + 6

L_y = 10

Hence: The coordinates of L is:

L = (-10,10)

PLZ HELP ME!!
marissa [1.9K]

Answer:

200 trucks

Step-by-step explanation:

There's about 15 trucks in the 2nd row from the right. It looks to be about 1/2 the size of the rows to the left of it.

So based on that, I can assume, there are about 30 trucks in each of the 5 long rows, and both of the short rows would make up about another 30 trucks total. There are various trucks parked along the perimeter or between rows, so I estimated there would be about 20 of those based on 3 per row.

30 x 5 = 150 +30 = 180 + 20 = 200

The answer is 15%

Explanation:

Team A has 42 members and team b has 18 more than team A so team b has 60 members. In order for the teams to be equal, there’d need to be 51 people on each team(60+42/2=51). There are 9 extra people on team b, so we need 9/60 , divide and you get 15%.
