50 dollars plus 2dollars , x representing how many umbrellas are being rented, and y representing how many chairs are rented
Answer:
use the distributive property
Step-by-step explanation:
Use the distributive property to rewrite the expression with the GCF factored out.
<u>Example</u>:
ab +ac +ad . . . . has terms with a common factor of 'a'
When the common factor is factored out, the distributive property tells you the equivalent is ...
= a(b +c +d)
If 'a' is the greatest common factor, then b, c, d are mutually prime and no more factors can be removed to outside the parentheses.
Answer:
1154
Step-by-step explanation:
Perhaps the easiest way to evaluate this numerical expression is to let a calculator do it. Alternatively, we can compute the value from a +1/a.
__
<h3>expression</h3>
Consider the square of a +1/a:
(a +1/a)^2 = a^2 +2(a)(1/a) +1/a^2 = (a^2 +1/a^2) +2
This means ...
a^2 +1/a^2 = (a +1/a)^2 -2
Similarly, using a^2 for 'a' in the above, we have ...
a^4 +1/a^4 = (a^2 +1/a^2)^2 -2
<h3>numerical value</h3>
The value of a +1/a is ...
Then the value of a^2 +1/a^2 is 6^2 -2 = 34
and the value of a^4 +1/a^4 is 34^2 -2 = 1154
2:4 is the probability. It is more likely to receive a ordinary quarter, but the probability of the two headed quarter is still great enough to get it.
X=6 and CD Is 11 and AB is 9
