Find HCF of Question number 23

trapecia [35]

Answer: x - 2

Step-by-step explanation:

HCF is more commonly referred to as GCF (greatest common factor)

Factor each expression to see which factor(s) they have in common.

$x^4 - 8x\implies x(x^3-8)\\= x\boxed{(x-2)}(x^2+4x+4)\\\\\\3x^2-8x+4\implies 3x^2-6x-2x+4\implies3x(x-2)-2(x-2)\\=(3x-2)\boxed{(x-2)}\\\\\\2x^2-5x+2\implies 2x^2-4x-x+2\implies 2x(x-2)-1(x-2)\\=(2x-1)\boxed{(x-2)}$

The only factor that all three expressions have in common is: x - 2

Describe how to compare the two ratios 5:8 to 7:9. Tell each step to set up the ratios, then explain what to do to be able to co

Lera25 [3.4K]

Step-by-step explanation:

The ratio's can be expressed as fractions and you may compare those.

5 : 8 = 5/8
7 : 9 = 7/9

In order to compare fractions you need to bring them into equal denominator.

8 and 9 have LCM of 8*9 = 72 since they have no common factors.

The equivalent fractions with common denominator are:

5/8 = 9*5/(9*8) = 45/72
7/9 = 8*7/(8*9) = 56/72

Now we can compare the fractions:

45/72 < 56/72, since 45 < 56
