Two numbers multiply together to make 8, but add together to make - 6 What are the two numbers?

Greeley [361]

Answer:

-4 and -2

Step-by-step explanation:

First find all the factors of 8, that would be 1 and 8, -1 and -8, 2 and 4, and -2 and -4.

Then, adding the groups of numbers you have should show you what would equal -6. So 1 + 8 = 9, -1 + (-8) = -9, same vice versa, 2 + 4 = 6, -2 + (-4) = -6. So -2 and -4 would be your two numbers.

Which expression is equivalent to the following complex fraction?

svlad2 [7]

Consider the fraction first ;

${:\implies \quad \sf \dfrac{\dfrac{3}{(x-1)}-4}{2-\dfrac{2}{(x-1)}}}$

${:\implies \quad \sf \dfrac{\dfrac{3-4(x-1)}{\cancel{(x-1)}}}{\dfrac{2(x-1)-2}{\cancel{(x-1)}}}}$

${:\implies \quad \sf \dfrac{3-4x+7}{2(x-1-1)}}$

${:\implies \quad \boxed{\bf{\dfrac{-4x+7}{2(x-2)}}}}$

Hence, Option B) is required answer

A cylindrical can is to have volume 1500 cubic centimeters. determine the radius and the height which will minimize the amount o

Degger [83]

Assuming R and H:
So volume is pir^2 * H = 1500 and H = 1500/(pir^2) while surface area is A= 2pir*H + 2pir^2
A = 2pir(r+h)= 2piR^2 + 2pir*1500/(pir^2)= 2piR^2 + 3000/r
For A to take minimum, get the derivative 4pir - 3000/R^2 and let it be 0
4pir^3 - 3000 = 0
r = cbrt(3000/(4pi)) ≈ 6.20
h = 1500/(pi(6.20)^2) ≈ 12.42
