Which expression is equal to x + (f+g)? (1 point)
Answer:
x + f(x) + g(x)
Step-by-step explanation:
(f+g) = f(x) + g(x)
Therefore, x + (f+g) = x + f(x) + g(x)
If you are given equations to go with f(x) and g(x), you would plug in those equations to the above expression then combine like terms to find the fully simplified expression equal to x + (f+g).

17. A triangle has sides of length x, X -3 And x+6 what is the perimeter of the triangle?
A.3x+3
B.3x^3+3
C.3x^3+18
D.3x+9
Answer:
A. 3x+3
Step-by-step explanation:
The perimeter is found by adding all the side lengths:
(x)+(x-3)+(x+6)
=1x+1x+1x-3+6
=3x+3
(Remember, add x-terms to x-terms, and numbers to numbers)

To compare two products such as colas, a random sample is selected to taste two types of colas (A and B). Each selected subject tastes both colas and selects his/her preferred cola. What sample size would be needed to ensure that the margin of error in the brand preference is less than 5 percentage points in more than 95% of experiments
Answer: The sample size would be needed = 385
Step-by-step explanation:
Let p be the prior population proportion.
Margin of error = E
When not estimate of p is given , the formula to calculate the minimum sample size n = [tex]0.25(\dfrac{z^*}{E})^2[/tex] , where z* = critical value for given confidence interval.
Here z* for 95% confidence level is 1.96.
E=5%=0.05
Then [tex]n=0.25(\dfrac{1.96}{0.05})^2\approx385[/tex]
Hence, the sample size would be needed = 385

A cone has a diameter of 18 units and height of 8 units. What is its volume?
A. 721 cubic units
B. 21617 Cubic units
C. 64817 cubic units
D.8641 cubic units
Answer: I hope this helps!
Step-by-step explanation:
The volume of cone having diameter 18 units and height 8 units is 678.85 cubic units which is nearest to 648.17 cubic units which is option C.
What is volume?Volume is basically amount of substance a container can hold in its capacity. Volume of cone is 1/3 *π[tex]R^{2}H[/tex] in which R is the radius and H is height of cone.
How to find volume?We know that volume of cone is 1/3 *π*[tex]R^{2} H[/tex]
We have to put the value of radius and height in the formula to get the value of volume of cone.
Radius=diameter/2
=18/2
=9 units.
Volume=1/3 * 3.14*9*9*8
=2034.72/3
=678.24 cubic units
Nearest option is 648.17 cubic units.
Hence the volume of the cone is 648.17 units.

2. When you take a taxi, the driver charges an initial fee
when you start a ride and then an additional charge for
every mile driven in the cab. If the total fare for a cab
ride is 3.5m + 2.5 after riding for m miles, what does the
2.5 represent? Explain (use appropriate math
vocabulary in your explanation).
Answer:
The
3
mile cab ride includes a basic charge as well as the cost for the distance covered.
For a
6

$
4.80
which means that :
The cost of

A person is looking from a car to the top of a building. The angle of elevation to the top of the building from the car is 32°. The building is 200 feet away. How tall is the building? Round to the nearest foot.
Answer:
132.2 ft
Step-by-step explanation:
This is a right angle problem where 32 is the angle and 200 feet is the leg unederneath. To solve for the height we use tangent since we have the adjacent side and we are solving for the opposite side.
Steps:
1. tan32 = x/200
2. (tan32)200=x
3. x=132.2 ft
Find an equation of the line that passes through (6,-1) and has a slope of 3
Answer:
The equation is: y y = 5/4 * x - 13
Step-by-step explanation:
The slope-intercept y = mx + c form of a straight line is In this case we have a point, (x, y) and the slope, m so all we need is a value for c. Substitute into y = mx + c - 3 = 5/4 * (8) + c - 3 = 10 + c c = - 13 y = 5/4 * x - 13 The equation is: y the formula for the situation have a point, (x 1 ,y 1 ) and the slope, Or you can use where you (m) y-y 1 =m(x-x 1 ) y - (- 3) = 5/4 * (x - 8) y + 3 = 5/4 * x - 10 y = 5/4 * x - 13 Answer link < II

Solve: (x −6)−(4.5−x )= −1.5
PLZ HELP
Answer:
x=9/2 Hope this helps!
Step-by-step explanation:
Let's solve your equation step-by-step.
x−6−(4.5−x)=−1.5
Step 1: Simplify both sides of the equation.
x−6−(4.5−x)=−1.5
x−6+−1(4.5−x)=−1.5(Distribute the Negative Sign)
x+−6+(−1)(4.5)+−1(−x)=−1.5
x+−6+−4.5+x=−1.5
(x+x)+(−6+−4.5)=−1.5(Combine Like Terms)
2x+−10.5=−1.5
2x−10.5=−1.5
Step 2: Add 10.5 to both sides.
2x−10.5+10.5=−1.5+10.5
2x=9
Step 3: Divide both sides by 2.
2x/2=9/2
x=9/2
Answer is 9/2.
