Start with the smallest number, 18:

      The factors of 18 are: 1, 2, 3, 6, 9, 18.

So the GCF for all three must be one of those.

Now consider the next smallest number.  Of the factors of 18, only these are also factors of 27:

    1, 3, 9

Now consider the last number, 54.  Of the remaining factors, 9 is the greatest and 9 goes into 54.

The GCF is 9.

By starting with the smallest number, you usually limit how many factors you'll ever need to consider.

A plane intersects a prism to form a cross section that is a polygon with five sides. The minimum number of sides that the polyg
antoniya [11.8K]

Answer:

Since the plane if cutting through the prism to make 5 sides, than the original shape needs to have less than 5.

A prism, is a 3D shape, so you can't have a 2 sided shape.

Now you have a choice of 3+or 4 sides.

A 3 sides shape is a triangle, which also can't be cut into a 5 sided prism, so the answer would need to be 4.

Given the equation (x+a)^2(x-2)=x^3+bx^2+12x-72 find a and b
GaryK [48]
Isolate the variable by dividing each side by factors that don't contain the variable.

a=-  \frac{ x^{2}-  \sqrt{( x^{3} + x^{2} b+12x-72(x-2)-2x} }{x-2} ,-  \frac{ x^{2}+  \sqrt{( x^{3} + x^{2} b+12x-72(x-2)-2x} }{x-2}

Solve for b by simplifying both sides of the equation then isolating the variabel.

b= \frac{12}{x}+ \frac{72}{ x^{2} }-2+2a- \frac{4a}{x}+ \frac{ a^{2} }{x}- \frac{2a^{z} }{ x^{2} }
