If you would like to know the value of A, you can do this using the following steps:
3x^2 + 9x - 4 = 0
3x^2 + 9x = 4
<span>A(x^2 + 3x) = 4
</span>A = 3:
<span>3 * (x^2 + 3x) = 4
</span>3x^2 + 9x = 4
The correct result would be C: 3.
The concept that can be used in order to measure the given item is the ratio and proportion. The ratio of Nicole's height to her shadow at that particular time should be equal to the ratio of the height of the tower to its shadow. If we let x be the height of the tower then, the equation would be,
x/20 feet = 5 ft/80 inches
The units of the denominators should be equal to have a reasonable comparison, let us convert 80 inches to feet by dividing it by 12 to get the answer of 20/3 ft.
x/20 = 5/(20/3)
The value of x from the equation is equal to 15 ft.
Answer: 15 ft.
36. You can search it up and look at a times table chat or you can do this 6x5=30+6=36
nothing can further be done with this?
