The figures below are rectangles. Which polynomial represents the area of the shaded region? HAVE ALL MY POINTS but answer truthfully cause i have the answer choices
Answers
Answer:
[tex] 7x - 1 [/tex]
Step-by-step explanation:
Area of the shaded region = area of the large rectangular - area of the small rectangle
Area of rectangle is given as l*w
Area of the large rectangle = [tex] l*w = (x + 5)(x - 1) [/tex]
Expand
[tex] = x(x - 1) +5(x - 1) [/tex]
[tex] = x^2 - x + 5x - 5 [/tex]
Area of large rectangle [tex] = x^2 + 4x - 5 [/tex]
Area of small rectangle = [tex] l*w = (x + 1)(x - 4) [/tex]
[tex] = x(x - 4) +1(x - 4) [/tex]
[tex] = x^2 - 4x + x - 4 [/tex]
Area of small rectangle = [tex] = x^2 - 3x - 4 [/tex]
Area of shaded region = [tex] (x^2 + 4x - 5) - (x^2 - 3x - 4) [/tex]
[tex] = x^2 + 4x - 5 - x^2 + 3x + 4 [/tex]
Collect like terms
[tex] = x^2 - x^2 + 4x + 3x - 5 + 4 [/tex]
[tex] = 7x - 1 [/tex]

Answers
Answer:
42.25 square inches
Step-by-step explanation:
the formula for area of a square is length x width
a square has four equal sides
so the length and width of the square are 6.5
so you would multiply 6.5 by itself: 6.5x6.5=42.25
so the tile overs 42.25 sq inch

Step-by-step explanation: It isn't one of the perfect squares. For example, the first 10 perfect square are 1, 4, 9, 16, 25, 36, 49, 64, 81, and 100.
Answer:
it is an irrational number and here is why
Step-by-step explanation:
So think of square root as it's answer is something that you you multiply its self by its self and you get that answer. Ex: 8 x 8 = 64 square root of 64 is 8. So in that case there is nothing you can exactly multiply by itself to get 7 so in that case it's a decimal or an irrational number.

A local library claims it has 2.73x103 books. If there are 42 people in the building, how many books per capita are there?
Answers
Answer:
63 books per capita in the library
Step-by-step explanation:
Given
[tex]Books = 2.73 * 10^3[/tex]
[tex]People = 43[/tex]
Required
Determine the book per capita
To do this, we simply divide the number of books by number of person;
[tex]Average = \frac{Books}{People}[/tex]
[tex]Average = \frac{2.73 * 10^3}{43}[/tex]
[tex]Average = \frac{2.73 * 1000}{43}[/tex]
[tex]Average = \frac{2730}{43}[/tex]
[tex]Average = 63.488372093[/tex]
[tex]Average = 63[/tex] (Approximated)
Hence;
There are 63 books per capita in the library

calculate the length of the base of a parallelogram if the area is 135cm and it's height is 9cm
Answers
Answer:
15cm
Step-by-step explanation:
The formula to calculate the area of a parallelogram is base x height.
Since we know the height and area, we can write the equation:
135 = base x 9
Now we can just divide 9 from both sides to solve for base:
135/9=basex9/9
So we get:
Base = 135/9=15
The length of the base is 15cm.

What is the value of x & y?
Answers
Answer:
x = 16, y = 9
Step-by-step explanation:
The 2 triangles are similar by the AA postulate, thus the ratios of corresponding sides are equal, that is
[tex]\frac{x}{24}[/tex] = [tex]\frac{12}{18}[/tex] = [tex]\frac{2}{3}[/tex] ( cross- multiply )
3x = 48 ( divide both sides by 3 )
x = 16
----------------------------------------------------
[tex]\frac{y}{6}[/tex] = [tex]\frac{18}{12}[/tex] = [tex]\frac{3}{2}[/tex] ( cross- multiply )
2y = 18 ( divide both sides by 2 )
y = 9
