Answer» Answer: p² + p Step-by-step explanation: if p is a prime number, it does not have any common factors with (p+1) when 2 NUMBERS do not have a common FACTOR their lcm is their product so the LCM = p·(p + 1) = p² + p check: we can REPLACE p with some prime numbers e.g 2 => lcm of 2 and 3 = 6 (2 · 3) 11=> lcm of 11 and 12 = 132 (11 · 12)

23.

If p is the prime number than the lcm of p and (p+1) is

Answer»

Answer:

p² + p

Step-by-step explanation:

if p is a prime number, it does not have any common factors with (p+1)

when 2 NUMBERS do not have a common FACTOR their lcm is their product

so the LCM = p·(p + 1) = p² + p

check: we can REPLACE p with some prime numbers

e.g

2 => lcm of 2 and 3 = 6 (2 · 3)

11=> lcm of 11 and 12 = 132 (11 · 12)

28.

Two sides of a right angled tiangled are (2x+1) and (3x-2) and the perimeter is (6x+5)what is the length of the longest side if the perimeter is 65

Answer»

Step-by-step explanation:

Let the longest side be X UNITS

Remaining two sides are (2x+1) and (3x-2)

PERIMETER = 65 units

By condition

(2x+1)+(3x-2)+x = 65

2x+1+3x-2+x =65

2x+3x+x+1-2 = 65

6x-1 = 65

6x = 65+1

6x = 66

x = 66/6

x = 11

The longest side is 11 units

Represent 0.2161616...in the form of p/q

Answer»

Answer:

107/495 SIMPLIFY further if u can

Step-by-step explanation:

x = 0.2161616..... -eqaution 1

(multiply equation 1 with 10 )

10x = 2.1616..... -eqaution 2

(multiply equation 1 with 1000)

1000X = 216.1616..... -eqaution 3

now subtract equation 2 and 3

1000x-10x = 216.1616.... - 2.1616....

990x = 214

x = 214/990

x = 107/495 - final answer
