+3x−28 and g(x)=x+7g(x)=x+7, find f(x)+g(x)f(x)+g(x) and express the result in standard form.
9514 1404 393
Answer:
x^2 +4x -21
Step-by-step explanation:
Substitute the given expressions and simplify.
f(x) + g(x)
= (x^2 +3x -28) +(x +7)
= x^2 +(3+1)x +(-28 +7)
= x^2 +4x -21

The area of a parallelogram has the following formula: A=bh
Plug-in the given numbers.
Base=14cm
Height=13cm
A=bh
A=14 x 13
A=182
Therefore, the area of the figure is 182cm2
Answer: 182 square centimeters
Step-by-step explanation:
The formula for finding the area of a parrallelogram is A = bh. If the top measurement is 14 cm, then the bottom measurement is also 14 cm. The height is 13 cm.
A = (14) (13)
A = 182 cm^2
Parts of similar triangles.
If DEF~ JHI, find EF
Answer:
[tex]EF = 18[/tex]
Step-by-step explanation:
Given
[tex]\triangle DE\ F[/tex] similar to [tex]\triangle JHI[/tex]
Required
Find [tex]EF[/tex]
[tex]\triangle DE\ F[/tex] similar to [tex]\triangle JHI[/tex] implies that:
The corresponding sides are:
[tex]DE \to JH[/tex]
[tex]DF \to JI[/tex]
[tex]EF \to HI[/tex]
[tex]FG \to IK[/tex]
First, solve for x using the following corresponding ratios
[tex]EF : HI = FG : IK[/tex]
This gives:
[tex]x + 8 : 3x - 2 = 9 : 14[/tex]
Express as fraction
[tex]\frac{x + 8 }{ 3x - 2} = \frac{9 }{ 14}[/tex]
Cross multiply
[tex]14(x + 8) = 9(3x - 2)[/tex]
Open brackets
[tex]14x + 112 = 27x - 18[/tex]
Collect like terms
[tex]27x - 14x = 112 + 18[/tex]
[tex]13x = 130[/tex]
Solve for x
[tex]x = 10[/tex]
In the diagram, we have:
[tex]EF = x +8[/tex]
[tex]EF = 10 +8[/tex]
[tex]EF = 18[/tex]

Step-by-step explanation:
[tex] \frac{2}{3} x - 5 > 3 \\ \\ \frac{2}{3} x > 5 + 3\\ \\ \frac{2}{3} x > 8 \\ \\ x > 8 \times \frac{3}{2} \\ \\ x > 12[/tex]
I need to know the answer to this please and thank you, I don’t know how to do this.
Answer:
A= 30 sq feet
? = 5 feet
Step-by-step explanation:
if the total area is 104 square feet and we know where 44 square feet of that is accounted for that leaves 60 square feet so both A sections are equal so we can divide 60 by 2 to get 30 square feet. So "A" is 30 square feet.
to get "?" we need to find the other measurement for the 10 square foot sections, the easiest way to find that is 10 divided by 2 ( which is the measurement we already have), once we do this we get 5 feet, and because 5 feet is the height measurement for that part of the net diagram we know that the "?" will need to be 5 as well because it is also a height measurement.

Answer:A
Step-by-step explanation:
Austin checks the temperature at 10:00 p.m. He notices if the temperature
falls by 5 more degrees, it will break the record-low temperature for that date,
which is 26 degrees.
If t = the temperature in degrees at 10:00 p.m., which mathematical sentence
expresses the information above?
O A. t-5 < 26
B. t+ 5 < 26
O C. -5 > 26
O D. t+5 > 26
Answer:
A. t - 5 < 26°
Step-by-step explanation:
Record low temperature for that date = 26°
Temperature at 10:00 PM = t
A fall in temperature by 5° = t - 5
Thus, this is said would mean the record low temperature would be breaking at this point, meaning the new temperature low recorded will be less than 26°.
In mathematical expression, this is expressed as;
t - 5 < 26°

What is the distance between the points (-1,2) and (2,3).
9514 1404 393
Answer:
3.16 ≈ 3.2
Step-by-step explanation:
Put the numbers in the distance formula and do the arithmetic.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((2-(-1))² +(3-2)²) = √(3² +1²) = √10
d ≈ 3.16 ≈ 3.2
The distance rounded to hundredths is 3.16. Rounded to tenths, it is 3.2.

Identify the volume of a rectangular pyramid with length 16 m, width 12 m, and height 17 m.
Answer:
Correct Answer: 1088 m3
Step-by-step explanation:
To find the volume of the pyramid, first calculate the area of the base.
As the pyramid is rectangular, the base of the pyramid is a rectangle.
Use the formula for the area of a rectangle to calculate the area of the base.
B = lw
Substitute 16 for l and 12 for w.
B = 16 ⋅ 12
Simplify.
B = 192 m2
To find the volume of the pyramid, use the formula for the volume of a pyramid.
V = 1/3 Bh
Substitute 192 for B and 17 for h.
V = 1/3 ⋅ 192 ⋅ 17
Simplify.
V = 1088 m3
Therefore, the volume of the rectangular pyramid is 1088 m3.

Find the area of the sector MAG in terms of Pi and approximate to the nearest hundredth
Answer:
Area of sector MAG = 35.2π unit² (Approx.)
Step-by-step explanation:
Given:
Diameter MP = 26 unit
ARC MG = ARC IP
∠GAI = 30°
Find:
Area of sector MAG
Computation:
Radius = Diameter MP / 2
Radius = 26 / 2
Radius = 13 units
∠MAG = ∠IAP
So,
∠MAG + ∠GAI + ∠IAP = 180
∠MAG + 30 + ∠MAG = 180
2∠MAG = 150
∠MAG = 75°
Area of sector = [θ/360][π][r]²
Area of sector MAG = [75/360][π][13]²
Area of sector MAG = [0.2083][π][169]
Area of sector MAG = 35.2π unit² (Approx.)

A student wants to report on the number of movies her friends watch each week. The collected data are below: 2 14 1 2 0 1 0 2 Which measure of center is most appropriate for this situation and what is its value? (4 points) a Median, 1.5 b Median; 3 c Mean, 1.5 d Mean; 3
Answer:
The best measure of center for a set of data is the median value.
To find the median list the values from
Smallest to largest:
0, 0, 1, 1, 2,2, 2, 14
Since there is an even number of values, find the middle two numbers, add them together and divide by 2:
1+2 = 3
3/2 = 1.5
The answer is median 1.5

Solve the right triangle. 150 Find the length of the side adjacent to the given angle. (Round your answer to two decimal places.) Find the length of the hypotenuse. (Round your answer to two decimal places.) Find the other acute angle.
Answer:
62.12
15degrees
Step-by-step explanation:
Given
Opposite = x= 60
Angle of elevation = 75degrees
Required
Hypotenuse
Using the SOH CAH TOA identity
Sin theta = opp/hyp
Sin 75 = 60/H
H = 60/sin 75
H = 60/0.9659
H = 62.12
Hence the hypotenuse is 62.12
Since the sum of angle in a triangle is 180degrees, hence
75+90+x = 180
X is the unknown side
165 + x =180
x = 180-165
x = 15degrees
Hence the other acute angle is 15degrees
