WILL GIVE BRAINLIEST AND 20 POINTS! Find the LCM.
11, 13
STEP 1: Define the LCM (least common multiple).
The least common multiple (LCM) of two or more numbers is the smallest number that is a multiple of all the numbers.
The LCM can be found by first writing each number as a product of prime factors.
The LCM must contain all the prime factors of each number.

STEP 2: Determine the prime factorization of each number.
Determine the prime factorization of 11.
11 =

Determine the prime factorization of 13.
13 =

STEP 3: Multiply all of the prime factors.
11 ×
=
LCM =

143...is the lcm...

Step-by-step explanation:

lcm (11; 13) = 143: least common multiple, calculated. Numbers have no common prime factors: 143 = 11 × 13

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225
