The given expression has some variables and their values are also given in the question, so using the substitution method,
The value of is 38.
Given information:
The expression
where,
The value of x = 5,
The value of w = 2,
The value of y = 8,
And
The value of z = 3.
On putting the given values in the given expression and solving for the final answer as,
Hence ,by using the substitution method the value of is 38.

Answer:
Step-by-step explanation:
To find the value of x² + (2y) ÷(2w) +3z , first we substitute the values of w, x, y and z
5² + 2(8) ÷ 2(2) + 3(3)
To simplify this further, we have to apply the rule of BODMAS
(Applying the rule of BODMAS simply means when you have an equation, if its having bracket, you have to remove the bracket first, then you move to powers then you proceed to dividing then subtraction and then addition)
5² + 2(8) ÷ 2(2) + 3(3)
=25 +16 ÷ 4 +9
=25 + 4 +9
=38
Therefore the value of x² + (2y) ÷(2w) +3z is 38
Selling price-9.625
5.50*.75=4.125
5.50+4.125=9.625

Answer:
Carbon
Step-by-step explanation:
Carbon is a non metal but Graphite is a pretty good conductor of electricity which is an allotrope of Carbon. There are delocalised electrons which are free. These are responsible for conduction.
These arise because each carbon atom is only bonded to 3 other carbon atoms. The structure of Graphite provides for this arrangement. This leaves 1 electron to become delocalised.
Thus Graphite can be used for electrodes in batteries and for electrolysis.
Hello from MrBillDoesMath!
Answer:
(2^2) * 23
Discussion:
92 = 2 * 46 (every even number is divisible by 2)
92 = 2 ( 2 * 23) "
But 23 is prime so the prime factorization is (2^2) * 23
Thank you,
