Step-by-step explanation:
what is the sum 3/x^2-g + 5/x+3
======================================================
Work Shown:
[tex]\frac{3}{x^2-9} + \frac{5}{x+3}\\\\\frac{3}{x^2-9} + \frac{5(x-3)}{(x+3)(x-3)}\\\\\frac{3}{x^2-9} + \frac{5x-15}{x^2-9}\\\\\frac{3+5x-15}{x^2-9}\\\\\frac{5x-12}{x^2-9}\\\\\frac{5x-12}{(x+3)(x-3)}\\\\[/tex]
The idea is to get the denominators to be the same to the LCD (lowest common denominator). Note in step 2, I multiplied top and bottom by (x-3) to get this done. Then in step 3, I used the difference of squares rule to get x^2-9. Afterward, we can combine the fractions and like terms.

Mr. Smith plans to build a 3-foot-wide walkway
around the outside of the cabin, as shown in the floor
plan. What will be the area, in square feet, of the top
surface of the walkway?
A. 171
B. 324
360
396
720
Answer:
360
Step-by-step explanation:
The area of the top surface of rectangular cabin walkway is given by the equation A = 360 feet²
What is the Area of a Rectangle?The area of the rectangle is given by the product of the length of the rectangle and the width of the rectangle
Area of Rectangle = Length x Width
Given data ,
Let the area of the rectangular cabin be represented as A
Now , the initial length of the cabin = 30 feet
The initial width of the cabin = 24 feet
And , Mr. Smith plans to build a 3-foot-wide walkway around the outside of the cabin
So , the increased length of the rectangular cabin = 30 + 6 = 36 feet
The increased width of the rectangular cabin = 24 + 6 = 30 feet
Now , Area of Rectangle = Length x Width
Substituting the values in the equation , we get
Area of rectangular cabin A = 36 x 30
Area of rectangular cabin A = 1080 feet²
Now , the area of the cabin before increment of sides = 24 x 30
The area of the cabin before increment of sides = 720 feet²
So , the area of the walkway = 1080 - 720 = 360 feet²
Area of rectangular cabin walkway A = 360 feet²
Hence , the area of the rectangular cabin walkway is 360 feet²

Mark this and retum
Answer:
The representative sample contained more girls than boys.
Step-by-step explanation:
A "sample" of something is a small part of it. A "representative sample" is a small part of the students that represents them all. A random sample would not include all 160 students. It is more likely that there would be more girls than boys, than more boys than girls. In total, there are more girls than boys: 95 girls to 65 boys. It is more likely that a sample of the total students would be just like the total, but smaller.

Here are two sums
2/7 + 1/4 5/6 - 1/4
A В
Which of the two sums is closer in value to 1/2
You must show your working and state clearly whether the answer is A or b
Answer:
Step-by-step explanation:
[tex]\frac{2}{7}+\frac{1}{4}[/tex]
LCD = 28
[tex]\frac{2}{7}+\frac{1}{4}=\frac{2*4+1*7}{28}\\\\=\frac{8+7}{28}\\\\=\frac{15}{28}\\[/tex]
= 0.535 {Round off to tenth}
= 0.5
[tex]\frac{5}{6}+\frac{1}{4}=\frac{5*4-1*6}{24}\\\\=\frac{20-6}{24}\\\\=\frac{14}{24}\\\\=\frac{7}{12}\\[/tex]
= 0.583 {Round off to tenth}
= 0.6
So 2/7 +1/4 is closer to 1/2

Answer:
Line : y = ax + b, passes (0, 3) and (2, -3)
=> b = 3
=> 2a + b = -3
=> a = -6/2 = -3
=> Slope a = -3
=> Option D is correct
Hope this helps!
:)
Answer:
D is the answer
Step-by-step explanation:
Slope = rise / run
Slope = y2-y1 / x2-x1
Where coordinates are
(0,3),(2,-3)
So x1=0,y1=3 , x2=2 , y2= -3
Slope= -3-3/ 2-0
Slope = -6/2
Slope = -3
