Your question is not clear make it a little clearer I like to help ypu
Like terms are terms that have same variable. For example:
- 2x and x are like terms because they have same variable which is x.
- y and 3y both are like terms because they have same variable which is y.
- 2x and y both are not like terms because x-term and y-term are not the same variable or term.
The thing that you need to becareful is about the degree. Even though x² and x both are also x-term, but they are not considered like terms. So basically like terms are terms that have same variable and same degree.
Given the expression below:
From the expression:
- 2x and x are like terms.
- x² and x² are also like terms.
Arrange in better form for our calculation.
You might also want to arrange the expression degree (optional but recommended).
Answer
Answer:
|8|
Step-by-step explanation:
Let the integer = x
x = - 2x - 24
x + 2x = - 24
3x = - 24
x = - 24/3
x = - 8
Hence, the integer is - 8
The number could be the positive of negative of 8
Hence, it is better expressed as |8|
The answer would be 1 1/2
Answer:
95% confidence interval of the mean level of random exposure in tombs in the region.
(2746.868 , 4191.132)
Step-by-step explanation:
<u><em>Step(i)</em></u>:-
Given sample size 'n'= 12
Mean of the sample x⁻ = 3,469
and standard deviation of the sample 's' = 1,135
<em>95% confidence intervals are determined by</em>
Degrees of freedom = n-1 = 12-1= 11
<u><em>Step(ii)</em></u>:-
<em>95% confidence intervals are determined by</em>
( 3469-722.132 , 3469 +722.132)
(2746.868 , 4191.132)
