A football team lost five yards on each of two consecutive plays. Find the total change in yardage.
maria [59]

Answer:

The change is a loss of 10 yards, so -10 yards.

Step-by-step explanation:

The total change in yardage after 2 plays is the sum of the yardage of each play.

What lost yardage means?

Lost yardage means negative yardage.

Imagine that in a Buffalo Bills game, Devin Singletary lost 2 yards on his first carry. So his total yardage is -2.

If in the next carry he gets 3 yards, his total yardage is 1. If he loses 1, his total yardage is -3.

First play

Loss of 5 yards.

So the first play counts for -5 yards.

Second play

Loss of 5 yards.

So the second play counts for -5 yards.

Total

-5 - 5 = -10

The change is a loss of 10 yards, so -10 yards.

Find the area of a rectangle with length (3x+2) units with width ( 4x+10 ) units​
pantera1 [17]

Answer:

Step-by-step explanation:

Area of rectangle = length * width

 = (3x + 2)(4x + 10)

  = 3x *(4x + 10) + 2*(4x + 10)

 = 3x *4x + 3x *10 + 2*4x + 2*10

 = 12x² + <u>30x + 8x</u> + 20   {Combine like terms}

  = 12x² + 38x + 20

Given the following, find the value of x.<br> (4x+45)<br> (5x-18)
VladimirAG [237]

Step-by-step explanation:

Hey ..but there is nothing from which question can be equated ..

like if they are equal to zero..

or

(4x+45)=(5x-18)

i am giving answer for both scenarios

(4x+45)=0

4x=-45

x=-45/4

x=(-11.25)

(5x-18)=0

5x=18

x=18/5

x=3.6

Incase if they both are equal to each other...

(4x+45)=(5x-18)

(45+18)=(5x-4x)

63=x

x=63

Hope it helps you

Have a nice day

Briefly describe this graph of a Femis wheel.
son4ous [18]

Answer: This is a periodic relation.

Step-by-step explanation:

This is a periodic relation, that can be modeled with a sinusoidal relation, that relates the height as a function of time.

Then we can write this as h(t) = A*sin(C*t + F) + B

Where A is the amplitude, C is a constant that depends on the period, F is a phase shift, and B is the midpoint of the function.

2*A is the distance between the maximum height and the minimum height.

B is the middle height of the Femis Wheel.
