Answer:
See below in bold.
Step-by-step explanation:
f(x)=(x-15)(x+1)(x-10) = 0
The zeroes of the function are found as follows:
x - 15 = 0, so x = 15.
x + 1 = 0 and x - 10 = 0.
- in the same way -1 and 10 are also zeroes.
Answer:
it would range between 11.28379... to 13.819765...
Step-by-step explanation:
the circle's area formula is pi * radius^2
so you make to equation, plugging the 100 and 150 into the circle's area
you get square root of (100/pi) which gets 11.28379... for the area of 100
you do the same with 150 to get square root of (150/pi) which gets 13.819765...
those are the diameter of the circle since the diameter is double the radius which i already multiplied afterwards. so if you need the radius divide the number ive given you
Answer:
The number is 12
Step-by-step explanation:
4 times a number is 8 more than 40
Write the equation
4n=40+8
4n =48
Divide each side by 4 to isolate n
4n/4 = 48/4
n = 12
Answer:
Step-by-step explanation:
<u>Area of rectangle:</u>
<u>Given:</u>
<u>The area is:</u>
A = (2x - 7)(3x² + 4x) =
2x(3x² + 4x) - 7(3x² + 4x) =
6x³ + 8x² - 21x² - 28x =
6x³ - 13x² - 28x
