First what you should do is subtract the 2 on both sides
You’ll get px = 4x+x+7 then add the x to 4x
Px= 4x^2 +7
Dived the x on the left on both sides like this px/x = 4x^2+7/x
P= 4x+7

Sierra has plotted two vertices of a rectangle at (3,2) and (8,2). What is the length of the sides of the rectangle
Answers
Answer:
5units
Step-by-step explanation:
Given the two vertices of a rectangle at (3,2) and (8,2). We are to calculate the distance between the two points.
Using the formula
D = √(x2-x1)²+(y2-y1)²
D = √(2-2)²+(8-3)²
D = √0+5²
D = √25
D = 5
Hence the length of the side of the rectangle is 5units

Solve for the area of the figure below and show work.
Answers
Answer and Step-by-step explanation:
1. We can see that this kite-shape has 4 triangles in it.
The area of a triangle is as follows:
[tex]A = \frac{bh}{2}[/tex]
Where:
b = Base (length)
h = Height
Top Right Triangle Area:
b = 9
h = 3
A = [tex]\frac{3 * 9}{2}[/tex]
A = [tex]\frac{27}{2}[/tex]
Bottom Right Triangle Area:
b = 9
h = 3
A = [tex]\frac{3 * 9}{2}[/tex]
A = [tex]\frac{27}{2}[/tex]
Top Left Triangle Area:
b = 4
h = 3
[tex]A = \frac{4*3}{2}[/tex]
A = [tex]\frac{12}{2}[/tex]
A = 6
Bottom Left Triangle Area:
b = 4
h = 3
[tex]A = \frac{4*3}{2}[/tex]
A = [tex]\frac{12}{2}[/tex]
A = 6
Now, we add all the areas together to get the area of the kite figure.
A = [tex]\frac{27}{2}[/tex] +
A = 27 + 12
A = 39
The area of the kite figure is 39 [tex]m^{2}[/tex].
2. We have to find the area of the trapezoid.
(I'm not sure if the 9 is for the entire bottom side length)
If the bottom side length is 9, then we would use the formula:A = [tex]\frac{a + b}{2} h[/tex]
to find the area of the entire trapezoid.
A = [tex]\frac{2.4 + 9}{9}[/tex] × 8.2
A ≈ 46.74 [tex]mi^{2}[/tex]

Solve the equation on the interval [0,2pi)
Answers
The value of θ within the interval is 210 and 330 degrees
Given the equation;
[tex]2sin^2 \theta = 5sin \theta - 3[/tex]
Let P = sinθThe equation will become;
2P² = 5P - 3
2P² - 5P - 3 = 0
Factorize;
2P² - 6P + P- 3 = 0
2P(P-3) + 1(P -3) =0
2P + 1 = 0 and P - 3 = 0
p = -1/2 and 3
Since P = sinθ
sinθ = -1/2
θ = -30 degres
Since sine is negative in the second 3rd and 4th quadrant
θ = 180 + 30 = 210 degrees
θ2 = 360 - 30 = 330 degrees
Hence the value of θ within the interval is 210 and 330 degrees

Step-by-step explanation:
Hello.
The Distributive Property states that
a(b+c)=ab+ac
Where
a, b, and c can be either constants or variables
we distribute a by multiplying it times b and c, and simplify if necessary.
In this case, we should distribute 12:
12(a-5)
12 times a and 12 times (-5):
12a-60
And we're done!

1. A line has a slope of 6 and includes the
points (-1, q) and (0, -7). What is the
value of q?
Answers
Answer:
q = - 13
Step-by-step explanation:
Calculate the slope m using the slope formula and equate to 6
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 1, q) and (x₂, y₂ ) = (0, - 7)
m = [tex]\frac{-7-q}{0+1}[/tex] = - 7 - q , then
- 7 - q = 6 ( add 7 to both sides )
- q = 13 ( multiply both sides by - 1 )
q = - 13
Answer:
q = -13?
Step-by-step explanation:
the equation is y = mx + c
m is the gradient
c is the y-intercept
where the line crosses the y axis
If 6 is the gradient then the equation is
y = 6x + c
Find c by using the coordinates given:
-7 = ( 6× 0) +c
-7 = 0 + c
c = -7
the equation is y = 6x -7
Substitute the other coordinates to find q:
y or q = (6 ×-1) - 7
q = -6 -7
q = -13

The temperature drops to a rate of five degrees per hour. Be d the number of degrees that lowers the temperature. Be the number of hours you spend. What is the dependent variable?
Answers
Answer:
d, the number of degrees that the temperature was lowered by
Step-by-step explanation:
The dependent variable in this scenario would be d, the number of degrees that the temperature was lowered by. This is because the value of this variable depends on the actual amount of hours that have passed by. Therefore, depending on the number of hours, the value of d could be completely different. The variable h for the number of hours does not depend on any other variable in the equation and has its own value, but since d depends on h then it would be the dependent variable in this scenario.
