Answer:

1,000 feet

Step-by-step explanation:

From point Q to point R, the x values change by 20 units while the y values stay the same. This side of the polygon has a length of 20

From point R to point S, the y values change by 30 units while the x values stay the same. This side of the polygon has a length of 30

From point S to point T, the x values change by 20 units while the y values stay the same. This side of the polygon has a length of 20

From point T to point Q, the y values change by 30 units while the x values stay the same. This side of the polygon has a length of 30

The total perimeter is 20 + 30 + 20 + 30 = 100 units, each unit represents 10 feet, so the total perimeter is 100(10) = 1,000 feet

Answer:

100 feet

Step-by-step explanation:

side lengths:

y2-y1 = /-10-10/ = 20 units

x2-x1= /20-(-10)/ = 30 units

20+20+30+30 = 100

12. Si R(x)=-5x2+x-2 y S(x)=-x - 3x, se<br>¿cuál es el resultado de R(x) + S(x) ?

Answer:

El resultado eres: $R(x) + S(x) = -6x^2 - 2x - 2$

Step-by-step explanation:

Se dan las siguientes funciones

$R(x) = -5x^2 + x - 2$

$S(x) = -x^2 - 3x$

Cuál es el resultado de R(x) + S(x) ?

Se soman los fatores en comun. Entonces:

$R(x) + S(x) = -5x^2 + x - 2 + (-x^2 - 3x) = -5x^2 + x - 2 - x^2 - 3x = -5x^2 - x^2 + x - 3x - 2 = -6x^2 - 2x - 2$

El resultado eres: $R(x) + S(x) = -6x^2 - 2x - 2$

Gabrielle and Rob each earn $22 an hour, and each works 40 hours this week. Rob spends 1/2 of his earnings this week on bills an

Zielflug [23.3K]

The amount spent is an illustration of subtraction and proportions

The amount left in his earnings is $414.25

<h3>How to determine the amount left in his earnings?</h3>

The given parameters are:

Rate = $22 per hour

Time = 40 hours

So, the total earnings is:

Total = $22 * 40

Evaluate

Total = $880

He spent half on bills.

So, we have:

Bills = 0.5 * $880

Bills = $440

He buys a video game for $25.75

So, the amount left is

Amount left = $880 - $440 - $25.75

Amount left = $414.25

Hence, the amount left in his earnings is $414.25
