The total area of both plots of land is?

VikaD [51]

You have 2x^2 + 9x -9 and 3x^2 -2x +14

To find total area add the two polynomials together by combining the like terms.

2x^2 + 3x^2 = 5x^2

9x + -2x = 9x-2x = 7x

-9 + 14 = 5

Total area = 5x^2 + 7x + 5

Answer:

x = 36

y = 37.95

Step-by-step explanation:

By geometric mean property:

${12}^{2} = 4 \times x \\ \\ 144 = 4 \times x \\ \\ x = \frac{144}{4} \\ \\ x = 36 \\ \\$

By Pythagoras Theorem:

${y}^{2} = {12}^{2} + {x}^{2} \\ \\ {y}^{2} = {12}^{2} + {36}^{2} \\ \\ {y}^{2} = 144 + 1296 \\ \\ {y}^{2} = 1440 \\ \\ y = \sqrt{1440} \\ \\ y = 37.95$

A truck begins a trip of 1675 miles. The truck averages 55 miles per hour, including stops. create a table, a graph, and an equa

lawyer [7]

Let
x be the distance that the truck has left to travel
t be the the time

The total distance is 1675 miles
The average speed is 55 miles per hour

The equation that represents the distance that the truck has left to travel with respect to time is
55t + x =1675
x = -55t + 1675
