<h3>By Associative property of multiplication,</h3>
<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>
We have to use the associative property of multiplication
<em><u>Associative property of multiplication</u></em>
When we are multiplying two or three numbers, it does not matter where we put the parenthesis, it results in same answer
Therefore,
Thus associative property of multiplication is used to find solution
Part one of your questions would be 1/20
Part two would be 1/20
Part three. Yes they are equal
Part four. None of them sense there equal
Since ABCD is a rectangle, AB and CD are parallel sides. This means that you can set AB equal to CD to solve for x. It would be:
1/2x+6=5/2x-2.
6=4/2x-2
8=2x
4=x
So the answer would be e. 4.
Hope this helps!
Hello :
8000 = 8 ×1000 = 2 ^3 ×10^3 = 20 ^3
note; identity b^3 +a^3 = (a+b) (a²+b² - ab)
in this exercice : b=20
so : 8000+b^3 = (a+20)(a²+400 - 20a).... <span>Factor the following</span>
Answer: 3/16
Step-by-step explanation: To multiply fractions, first multiply across the numerators and then multiply across the denominators.
× 
= ?
15 × 1 = 15
20 × 4 = 80
can be reduced by dividing both the numerator and denominator by the Greatest Common Factor which is 5.
15 ÷ 5 = 3
80 ÷ 5 = 16
Therefore, × =
