Answer:

Step-by-step exAnswer:(-2, 2)

Step-by-step explanation:

7q² - 28 = 0

Add 28 to bothside

7q² - 28 + 28 = 0+ 28

7q² = 28

Divide bothside by 7

7q² / 7 = 28/7

q² = 4

Take the square root of bothside

√q² = ±√4

q = ± 2

q = -2 or q =2

q = (-2, 2)

30 meter building casts a shadow the distance from the top of the building to the tip of the shadow is 37 M find the length of t
Pavlova-9 [17]

Answer:  22 meters

<u>Step-by-step explanation:</u>

Draw a picture of a right triangle and label the height as 30 meters and the hypotenuse as 37 meters.  Use the Pythagorean Theorem to find the base (the length of the shadow).

a² + b² = c²

x² + 30² = 37²

x²          = 37² - 30²

x²          = 1369 - 900

x²          = 469

√x²       = √469

        x = 21.656

        x ≈ 22
