Answer:

The correct answer is -5 and -9

Step-by-step explanation:

To find the answer here, first factor the equation.

x^2 + 4x + 45 = 0

(x + 9)(x + 5) = 0

Now set each parenthesis equal to 0 and solve.

x + 9 = 0

x = -9

x + 5 = 0

x = -5

Naya [18.7K]
First let’s call the square shape A and the rectangle shape B.

To find the area of shape A you do 24 x 24 = 576cm squared

To find the area of shape B you do 40 x 24 = 960cm squared

To find the total area you just add the two areas together
576 + 960 = 1536cm squared

What is the slope of line a?
marta [7]

Answer:

-1/3

Step-by-step explanation:

Slope is defined as "rise over run". If you count out the units, you should be able to see that your rise is 1 and your run is 3 and is pointing downward, so your answer is -1/3.

Alternatively you could use Slope Formula: m = \frac{y2-y1}{x2-x1}

At 2063 ft, the KVLY-TV tower in North Dakota is the world’s tallest supported tower. How long would it take an object to fall f
IgorLugansk [536]
Use the equation of motion under gravity:-

s =  16t^2    where s is the distance and t = time

2063 = 16t^2

t^2 = 2063 / 16 =  128.94 s

t = sqrt 128.94  =  11. 4 seconds to the nearest tenth of a second
