Given:
The area model.
The area of the shape is 82 square units.
To find:
The correct equation for the given situation.
Solution:
We know that, area of a rectangle is
[tex]Area=Length \times Width[/tex]
The figure is divided into 3 rectangles. Using this formula, the area of each rectangle is
[tex]A_1=(x)\times (3x)=3x^2[/tex]
[tex]A_2=(x)\times (4)=4x[/tex]
[tex]A_3=(3)\times (3x)=9x[/tex]
Now, the total area is equation to 82 square units.
[tex]A_1+A_2+A_3=82[/tex]
[tex]3x^2+4x+9x=82[/tex]
[tex]3x^2+13x=82[/tex]
Since the required equation is [tex]3x^2+13x=82[/tex], therefore, the correct option is C.

E. None of the above
Answers
Answer:
C -2/3
Step-by-step explanation:
Answer:
C. m = -2/3
Step-by-step explanation:
Slope is rise/run (rise-over-run).
It falls 2, so the "rise" is -2. It moves right by 3, so the "run" is 3.
Therefore, -2/3.

How do you find the missing height of a triangle?
Answers
Answer:
Use the Pythagorean theorem
Step-by-step explanation:
The pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex] where a is a height, b is a height, and c is the hypotenuse, which is the longest side of a triangle. For example, if the triangle has two side with lengths of three and four we would put them into the equation to get:
[tex]3^{2} +4^{2} =c^{2}[/tex]
Simplify the equation to get:
[tex]9+16=c^2[/tex]
Add 16 and 9 to get 25 and take the square root of both sides:
[tex]\sqrt{25} =c[/tex]
The sqrt of 25 is 5. Therefore, the length of the hypotenuse, or c, is 5.
Answer:
Plug your values into the equation A=1/2bh and do the math. First multiply the base (b) by 1/2, then divide the area (A) by the product. The resulting value will be the height of your triangle.

Answer:

Step-by-step explanation:
Perimeter of ∆ ABC = Perimeter of ∆ PQR
3x + 9 + 3x + 8 + 3x = 3x + 3x + 4x + 3
9x + 17 = 10x + 3
17 - 3 = 10x - 9x
14 = x
.: x = 14
AB = 3x +9 = 3×14+9 = 42+9 = 51
BC = 3x +8 = 3×14+8 = 42+8 = 50
AC = 3x = 3×14 = 42
PQ = 3x = 3×14 = 42
QR = 3x = 3×14 = 42
PR = 4x +3 = 4×14+3 = 56+3 = 59

If Mike earns $1,200 in 40 hours, how
much does he make in 30 hours?
Answers
Answer:
$900
Step-by-step explanation:
Since 30 is 3/4 of 40, Mike makes 3/4 of what 1,200 is in 30 hours
3/4 of 1,200 is 900
Therefore, Mike makes $900 in 30 hours

Answers
Answer: B -4
Step-by-step explanation:
Value of coefficient of the squared term in the parabola's equation = -4
Correct option is B.
What is parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.
Given,
Vertex of parabola (h,k) = (3, 5)
y = 6 for x = -1
Parabola opens horizontally left side
Vertex-form equation of parabola
x = a(y - k)² + h
-1 = a(6 - 5)² + 3
-1 = a(1) 3
a = -4
Hence, -4 is value of coefficient of the squared term in the parabola's equation.
