UNO [17]2 years ago
5 0

Answer:

12x² +3x = 96

Step-by-step explanation:

x = 4(x + 3)( 3x - 8)

x =  (4x + 12) (3x - 8)

x = 4x(3x - 8) + 12(3x - 8)

x = 12x² - 32x + 36x - 96

x = 12x² + (-32x + 36x) - 96

x = 12x² + 4x - 96

0 = 12x² + 4x -x - 96

0 = 12x² + 3x -96

96 = 12x² + 3x  same as 12x² +3x = 96

Naya [18.7K]

Answer:

B.) 4,096 feet

Step-by-step explanation:

You were given a time, and time in the equation is represented by "t". To find the height, represented by "h", you just need to plug the given value in for "t" and simplify to find "h".

t = (1/4)√x                                         <--- Original equation

16 = (1/4)√x                                      <--- Plug 16 in "t"

64 = √x                                            <--- Divide both sides by (1/4)

4,096 ft = x                                    <--- Square both sides

UNO [17]
Area of triangle = (1/2)*base*height

20.335 = (1/2)*base*8.3

2*20.335 = base*8.3

(2*20.335) / 8.3 = base          Use your calculator.

4.9 = base

base = 4.9cm
