Answer:
p = 3x+10
Step-by-step explanation:
The attached diagram pretty much explains it.
The unknown dimension at the top was the subject of a previous problem. It is the difference in length between the two marked horizontal segments:
(2x +15) -(x) = x +15 . . . . . length of unmarked solid horizontal line
Similarly, the length of the unmarked vertical line on the right is the difference between the marked vertical lines:
(2x -5) -(x -5) = x . . . . . length of unmarked solid vertical line
__
The formula for the area of a rectangle is used to find the areas of the left-side and right-side rectangles. Respectively, those areas are ...
left-side area = x(2x -5)
right-side area = x(x +15)
Then the total area enclosed by the solid line is ...
x(2x -5) +x(x +15) = x(2x -5 +x +15) = x(3x +10)
__
The area of the lot extension is the product of its dimensions:
extension area = x·p
We want this to be the same as the area in the solid line, so ...
x·p = x·(3x +10)
Dividing by the coefficient of p (which is x), we have ...
p = 3x +10
Simplify the expression.

Write a unit rate for the situation.
270 miles in 6 hours
___miles per hour
Answer:
I believe it it 13 miles per hour.
Step-by-step explanation:
We know that an object travels 270 miles, so the rate is 270 miles.
---------------------------------
6 hours
1 mile = 5,280 feet 1 day = 24 hours
5,280 x 270 = 425,600 1 hour = 3600 seconds
270 miles = 425,600 feet 3600 x 6 = 21,600
3600 x 24 = 86,400
Fraction: Fraction:
425,600 feet 4,256 ft 21,600 sec 1
------- = ----- ------------ = -------- hour
5,280 feet 528 ft 86,400 sec 4
4,256/528 ÷ 1/4 = 4,256/528 x 4/1 (reciprocal) = 17,024/528 = 439/33 = 13

Simplify the expression.
3x3 - 2x2
Answer:
3x^3 - 2x^2
Step-by-step explanation:
This is the answer because for the equation 3x^3 - 2x^2, nothing further can be done to this equation since there are no like terms.
What is the solution?
Answer:
y=60 x=16
Step-by-step explanation:
the triangles are identical so 92+y=3y-28 so solve that for y:
-y +28
120=2y . /2 /2
60 = y so y=60
and 6x+2=3x+50 and solve that for x: which gets x = 16
Then are you supposed to plug it in to the numerical equvilant to the angles and sides becuase if so: B and E is 152, AC and DF are 98
Hope this helps and brainliest would be greatly appreciated! Thanks!

Step-by-step explanation:
the function of f (x) is defined by f (x)=4x+7. the inverse of f (x) is g (x). what is g (15)?
Answer:
g(15) = 2
General Formulas and Concepts:
Pre-Alg
Order of Operations: BPEMDASEquality PropertiesAlgebra I
Function inversesStep-by-step explanation:
Step 1: Define
f(x) = 4x + 7
g(x) = f⁻¹(x)
g(15) is x = 15
Step 2: Find inverse
Rewrite: y = 4x + 7Swap: x = 4y + 7Isolate y term: x - 7 = 4yIsolate y: (x - 7)/4 = yRewrite: y = (x - 7)/4Back-substitute: g(x) = (x - 7)/4Step 3: Evaluate
Substitute: g(15) = (15 - 7)/4Subtract: g(15) = 8/4Divide: g(15) = 2(2) A store is having a 20%-off sale on all merchandise. If Mai buys one item and saves $13, what was the original price of her purchase? Explain your reasoning. *
Answer:
$65
Step-by-step explanation:
Let
x = original price of the item
Mai buys one item and saves $13,
This means 20% of the original price of the item = $13
20% of x = 13
20/100 * x = 13
0.2 * x = 13
0.2x = 13
Divide both sides by 0.2
x = 13 / 0.2
= 65
x = $65
Therefore, the original price of the item is $65
Write the quadratic equation whose roots are 1 and -6, and whose leading coefficient is 5.
(Use the letter x to represent the variable.)
Answer:
[tex]f(x)=5x^2+25x-30[/tex]
Step-by-step explanation:
Quadratic Equation
If the roots of a quadratic equation are known, we can form the equation as follows:
[tex]f(x)=a(x-x_1)(x-x_2)[/tex]
where x1 and x2 are the known roots, and a is the leading coefficient.
We are given the roots as x1=1 and x2=-6, and the leading coefficient as a=5, thus:
[tex]f(x)=5(x-1)(x+6)[/tex]
Operating:
[tex]f(x)=5(x^2-x+6x-6)[/tex]
Simplifying:
[tex]f(x)=5(x^2+5x-6)[/tex]
Multiplying:
[tex]\mathbf{f(x)=5x^2+25x-30}[/tex]

At the U-Pack Shipping, the workers can unload 24 trucks in 8 hours. Which of the following is a correct unit rate for this situation?
1 over 3. of a truck per hour
1 over 3. of an hour per truck
3 hours per truck
1 truck per hour
Answer:
1 over 3. of an hour per truck.
Step-by-step explanation:
1/3 x 1 hour = 20 min.
20 min X 24 (each truck) = 480 mins
480 mins / 60 mins = 8 hours
1/3 of an hour per truck.

Use the drawing tool(s) to form the correct answer on the provided graph.
Graph the solution to the following linear equality in the coordinate plane 2x+y>4
9514 1404 393
Answer:
see below
Step-by-step explanation:
Setting x=0, you can find the y-intercept:
y = 4
Setting y = 0, you can find the x-intercept:
2x = 4
x = 2
The boundary line can be drawn through these intercept points, (0,4) and (2,0). Because the "equal to" case is not included, the boundary line will be dashed.
The y variable is on the open side of the comparison symbol (y>), so the shading is above the boundary line. That is where y-values are greater than those on the line.
