Why would you use the Associative property of multiplication to solve (10times4)times2

Answers

Answer 1

Answer: You would use the Associative Property of Multiplication because it makes the problem a lot easier.

Answer 2

Answer: You would use the associative property to help you because it allows you to switch around 2 to (10times2)times 4 or (4times2)times10 without changing your answer.

3 piano solos....each is 5/12 hr....
u can either add : 5/12 + 5/12 + 5/12 = 15/12 = 1 1/4 hrs

or u could multiply : 3 * 5/12 = 15/12 = 1 1/4 hs

Answers

so to complete the square in
ax^2+bx+c=d form

make sure a=1
subtract c from both sides
take 1/2 of b and square it
add that to both sides
factor perfect square

1x^2-1x-2=0
a=1
move c to other side
add 2 to oth sides
x^2-1x=2
take 1/2 of b and square it
1/2 of -1=-1/2
squaer it
1/4
add that to both sides
x^2-1x+1/4=2+1/4
factor left side
(x-1/2)=2+1/4

first blank is 1/2

2+1/4=8/4+1/4=9/4

blanks are
1/2 and 9/4

A rectangle porch is 4 feet wide. It is 3 times long as it is wideAlso find the perimeter of the porch

Answers

Label the width: 4ft
Label the length: 12ft (4ft for each segment).
Perimeter=12+12+4+4=32ft

Final answer:

The porch, forming a rectangle, is 12 feet long, as this is three times its width of 4 feet. By using the formula for the perimeter of a rectangle, we find the perimeter here is 32 feet.

Explanation:

The rectangle porch in this problem is 4 feet wide. We are also told that the length of the porch is 3 times its width. So, the length of the porch is 4 feet (width) x 3 = 12 feet. The perimeter of a rectangle is found using the formula: Perimeter = 2* (length + width). Plugging in the values we found, the perimeter of the porch is 2 * (12 feet + 4 feet) = 32 feet.
