Lcm of polynomials 5y^2 - 80 and y + 4

The Least Common Multiple of polynomials is

Step-by-step explanation:

Given : Polynomials and

To find : LCM of the given polynomials

Solution :

First we find the factors of the polynomial

Apply

The LCM of some numbers is the smallest number that the numbers are factors of.

The LCM of  5 is result of multiplying all prime factors, the greatest number of times they occur in either number.

So, LCM of 5 is 5

The LCM of (y+4)(y-4),(y+4) is the result of multiplying all factors, the greatest number of times they occur in either term.

So, LCM of (y+4)(y-4),(y+4) is (y+4)(y-4)

Therefore, The Least Common Multiple of polynomials is

answ9x x 3=

step-by-step explanation:

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
