Answer:
we conclude that:
[tex]3\sqrt{125}+4\sqrt{20}=23\sqrt{5}[/tex]
Hence, the last option i.e. [tex]23\sqrt{5}[/tex] is correct.
Step-by-step explanation:
Given the expression
[tex]3\sqrt{125}+4\sqrt{20}[/tex]
Combining the radical expressions
[tex]3\sqrt{125}+4\sqrt{20}[/tex]
let us first solve
[tex]3\sqrt{125}[/tex]
[tex]=3\sqrt{5^3}[/tex]
[tex]=3\sqrt{5^2\cdot \:5}[/tex]
Apply radical rule: [tex]\sqrt{ab}=\sqrt{a}\sqrt{b},\:\quad \:a\ge 0,\:b\ge 0[/tex]
[tex]=3\sqrt{5^2}\sqrt{5}[/tex]
Apply radical rule: [tex]\sqrt{a^2}=a,\:\quad \:a\ge 0[/tex]
[tex]=3\cdot \:5\sqrt{5}[/tex]
[tex]=15\sqrt{5}[/tex]
Thus,
[tex]3\sqrt{125}=15\sqrt{5}[/tex]
similarly solving
[tex]4\sqrt{20}[/tex]
[tex]=4\sqrt{2^2\cdot \:5}[/tex]
Apply radical rule: [tex]\sqrt{ab}=\sqrt{a}\sqrt{b},\:\quad \:a\ge 0,\:b\ge 0[/tex]
[tex]=4\sqrt{2^2}\sqrt{5}[/tex]
Apply radical rule: [tex]\sqrt{a^2}=a,\:\quad \:a\ge 0[/tex]
[tex]=4\cdot \:2\sqrt{5}[/tex]
[tex]=8\sqrt{5}[/tex]
Thus,
[tex]4\sqrt{20}=8\sqrt{5}[/tex]
so we get
[tex]3\sqrt{125}=15\sqrt{5}[/tex]
[tex]4\sqrt{20}=8\sqrt{5}[/tex]
so the expression becomes
[tex]3\sqrt{125}+4\sqrt{20}=15\sqrt{5}+8\sqrt{5}[/tex] ∵ [tex]3\sqrt{125}=15\sqrt{5}[/tex] , [tex]4\sqrt{20}=8\sqrt{5}[/tex]
[tex]=23\sqrt{5}[/tex] ∵ [tex]15\sqrt{5}+8\sqrt{5}=23\sqrt{5}[/tex]
Therefore, we conclude that:
[tex]3\sqrt{125}+4\sqrt{20}=23\sqrt{5}[/tex]
Hence, the last option i.e. [tex]23\sqrt{5}[/tex] is correct.

Using the chart, it shows the total amount that the retailer (the chip company) spends to make each bag of chips. We're looking at the $3 chip bag, so looking we can see that it costs the company $1.00 for each bag. If it costs $1 to make and it sells for $3, the profit is $2. This chart makes it easy because it calculates the total charts for you.

The value of x is 1/5 for equation 3 – 5x = 2
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 3 – 5x = 2
Three minus five times of x equal to two
We need to solve for x
3 – 5x = 2
Subtract 3 from both sides
3-3-5x=2-3
-5x=-1
Divide both sides by -5
x=-1/-5
x equal to one by five
x=1/5
Hence, the value of x is 1/5 for equation 3 – 5x = 2
