Larry plans to paint 2 walls in his room. the ceiling is 8 feet above the floor. one of the walls is 13 feet wide and the other is 10 feet wide. what is the area of the walls that larry plans to paint? 80 ft² 104 ft² 184 ft² 1040 ft²

1040

Step-by-step explanation:

multiply all 80 times 10 times 13

step-by-step explanation:

d would equal 12

in order to find the gcf of two numbers, first you need to find the prime factorization of each of the numbers. after you divide out the numbers as much as you can, you get:

36 = 2x2x3x3

84 = 2x2x3x7

from there, you can see which prime factors the two numbers have in common: 2, 2, and 3. then, you multiply the factors together to get 2x2x3=12.

you can double check this by dividing the two initial numbers by 12 to make sure 12 is a factor of them:

36/12 = 3

84/12 = 7

in your explanation, you pretty much give the definition of greatest common factors: that out of all the whole factors that 36 and 84 have in common, 12 has the greatest value.

hope this !
