Answer:
2x+8
Step-by-step explanation:
Here, you have to find the similar sides. x and x are both the same thing, while 3 and 5 are both integers (whole numbers).
You add the similar sides together, then that is your answer.
x + x= 2x, and 3+5= 8.
Note: Just because I said that x and x are the same doesn't mean that you can just add random numbers together in other questions.
Answer:
66.67% probability that all selected components function properly
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
The order in which the components are chosen is not important. So we use the combinations formula to solve this question.
Combinations formula:
is the number of different combinations of x objects from a set of n elements, given by the following formula.
In this question:
Desired outcomes:
2 components which function properly, from a set of 5. So

Total outcomes:
2 components, from a set of 6. So

Probability:

66.67% probability that all selected components function properly
<span>D-21.4=87.9 \ solve for D
add 21.4 to both sides
</span><span>D - 21.4 +21.4 =87.9 + 21.4
simplify
D = 109.3</span>
Answer:
1
Step-by-step explanation:
Co-efficient means the integer in front of the variable
The co-efficient for -4x^3 would be -4 like that
