Given:
[tex]4\sqrt{7}-2(2\sqrt{7}+\sqrt{3})+\sqrt{12}[/tex]
To find:
The value of given expression.
Solution:
We have,
[tex]4\sqrt{7}-2(2\sqrt{7}+\sqrt{3})+\sqrt{12}[/tex]
It can be written as
[tex]=4\sqrt{7}-2(2\sqrt{7}+\sqrt{3})+\sqrt{4\times 3}[/tex]
[tex]=4\sqrt{7}-2(2\sqrt{7}+\sqrt{3})+2\sqrt{3}[/tex]
Using distributive property, we get
[tex]=4\sqrt{7}-2(2\sqrt{7})-2(\sqrt{3})+2\sqrt{3}[/tex]
[tex]=4\sqrt{7}-4\sqrt{7}-2\sqrt{3}+2\sqrt{3}[/tex]
[tex]=0[/tex]
Therefore, the value of given expression is 0.

According to the formula pi r squared, for a circle with a radius of one unit the area equals pi.
For a circle with a radius of two units the area equals four pi. Ans = 16 pi units squared
For a circle with a radius of three units the area is nine pi.
A = 25 pi units squared, 36 pi units squared, 49 pi units squared... to 100 pi units squared.
So try this... given the formula for circumference of a circle C = pi * d or C = 2 p* r
What are the circumferences for these circles....
r = 1 unit
r = 2 units
r = 3 units
Now finish the pattern to r = 10 units...

Liz wants to buy a shirt for $25 how much will Liz’s shirt cost in a total if sales tax is 4%
26$
Step-by-step explanation:
1% = 4/100 * 25
1% = 1
25 + 1 = 26
Another way to solve
Percentage increase = 100% + 4%
104/100 = 1.04
1.04 * 25 =26

The following table shows the expressions that represent the sales of two companies:
Company: А B
Sales: 110(0.70)^x 430(1.90)^x
Which company has the largest percent of increase?
-Company A
-Company B
-Both Company A and Company B
-Neither Company A nor Company B
9514 1404 393
Answer:
company B
Step-by-step explanation:
The growth rate is 1 less than the growth factor. The growth factor is the base of the exponential term.
Company A
growth factor: 0.70
growth rate: 0.70 -1 = -0.30 = -30%
__
Company B
growth factor: 1.90
growth rate: 1.90 -1 = 0.90 = 90%
__
Company B has a higher growth rate than Company A. (Company A has decreasing sales, not increasing.)
Company B has a higher growth rate than Company A.

Pennies made after 1984 weigh 2.5 grams. How much would 10 pennies weigh?
Answer:
25 grams
Step-by-step explanation:
Pennies made after 1984 weigh 2.5 grams. How much would 10 pennies weigh?
From the above question:
1 penny = 2.5 grams
10 pennies = x grams
Cross Multiply
1 × x grams = 10 pennies × 2.5 grams
x grams = 25 grams.
Hence, the weight of 10 pennies is 25 grams
Sunny's Surf Shop sold 160 surfboards this week, which was 320 percent of the number of surfboards sold last week. How many surfboards did Sunny's Surf Shop sell last week? O 16 O 50 O 160 512
Let, the number of Surfboards sold last week = x
Then, x * 320% = 160
x * 3.20 = 160
x = 160/3.20
x = 50
In short, Your Answer would be Option B
Hope this helps!
(no need to give brainliest) :)
Answer:
The answer would be B, 50.

8. Find the x and y intercepts. 6x + 12y = 24
Answer:
x - intercept: 4
y - intercept: 2
Step-by-step explanation:
The way you find the x-intereceppt is to pretend that the 12y isnt there. Therfore making the equation 6x=24. Then 24 divided by 6 equals 4.
The same thing but for the y-intercpt. Take away the 6x making the equation 12y=24. 24 divivded by 12 equals 2.

can anyone help and explain why this is either proportional or not? urgent!! (it needs an explanation too)
Answer:
The answer is that the table is not a proportional relationship.
Step-by-step explanation:
It's not a proportional relationship because the number was not a constant variable.In order for the table to have a proportional relationship the number has to be the same for all of the ratios.
Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
Hope this helps!!
Find the coordinates of the point P that divides the directed line segment from A to B in the given ratio.
A(-6, 9), B(2, 1); Ratio 5 to 3
Given:
Point P divides the line segment AB in 5:3 where A(-6,9) and B(2,1).
To find:
The coordinates of point P.
Solution:
Section formula: If a point divide a line segment in m:n, then the coordinates of point are
[tex]\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
Point P divides the line segment AB in 5:3 where A(-6,9) and B(2,1). Using section formula, we get
[tex]P=\left(\dfrac{5(2)+3(-6)}{5+3},\dfrac{5(1)+3(9)}{5+3}\right)[/tex]
[tex]P=\left(\dfrac{10-18}{8},\dfrac{5+27}{8}\right)[/tex]
[tex]P=\left(\dfrac{-8}{8},\dfrac{32}{8}\right)[/tex]
[tex]P=\left(-1,4\right)[/tex]
Therefore, the coordinates of point P are (-1,4).
Percy has already walked 25 kilometers this week, plus he plans to walk 5 kilometers during
each trip to school. After 12 trips to school, how many kilometers will Percy have walked in
total?
Answer:
85
Step-by-step explanation:
He walked 25 already. So you have x=25. He walks 5 km during each trip. There are 12 trips. 5 times 12 is 60. x=25+60. So, 25 plus 60 is 85.
