(x - 8)² = 144

Take square root of both sides

(x - 8) = √144

x - 8 = 12

x = 12 + 8

x = 20

Original lawn is = 20 feet * 20 feet square

What is the value of the expression below when x = 3?<br> 10x2 – 7x + 10
QveST [7]

Answer:

79

Step-by-step explanation:

To find the value of 10x^2 – 7x + 10, when x = 3, simply plug in the value of x in the expression and solve as follows:

10(3)^2 – 7(3) + 10

10(9) – 21 + 10

90 – 21 + 10

79

The value of 10x^2 – 7x + 10, when x = 3, is 79

The map below shows the length of a proposed land bridge at Phil Hardberger Park. The length of the land bridge is represented b
anastassius [24]

Answer:

<h3>A. 50 yards.</h3>

Step-by-step explanation:

Given the coordinates of the length of PH as P(2,55)  and H(32, 15), to get the actual length of the land bridge from P to H, we will use the formula for calculating the distance between two points.

D = √(x₂-x₁)²+(y₂-y₁)²

PH = √(32-2)²+(15-55)²

PH = √(30)²+(-40)²

PH = √900+1600

PH = √2,500

PH = 50

Hence the actual length of the land bridge from P to H to the nearest yard is 50 yards.

Identify if the given equation represents exponential growth or decay.
charle [14.2K]

Answer:

The first is decay, seeing as it is in between 1 and 0

The second is growth, as it is greater than 1

Step-by-step explanation:

It's exponential growth when the base of our exponential is bigger than 1, which means those numbers get bigger. It's exponential decay when the base of our exponential is in between 1 and 0 and those numbers get smaller.
