The GCF of 8 and 40 is 8. Hope that helps.
The answer is 162 81pi/2
Hope this helps!
the area is (1/2) x pix 9^2 = 81pi over 218.9=162162-81pi over 2
Answer:
would it be 2,3,4,5,6,7,8,9,10,11,12 or 2,3,3,4,4,4,5,5,5,5, etc?
Would it not be 4:5 as a ratio?
Answer:
x = 2 + 6i, x - 6i.
Step-by-step explanation:
To factor this you need 2 numbers whose product is + 40 and whose sum is -4. There are no such numbers so we could use the method of completing the square:
x^2 - 4x + 40 = 90
x^2 - 4x = -40
(x - 2)^2 - 4 = -40
(x - 2)^2 = -36 - So the roots are complex numbers:
x - 2 = +/-√36
x = 2 + 6i, x - 6i.
