Answer:
Simplified expression: (2r+16)(2r+16)
if you need to combine like terms it would be 4r+32
Step-by-step explanation:
to distribute you multiply whatever is outside the parenthesis with everythign inside. 2*r= 2r, 2*8= 16
(2r+16)(2r+16)
and if you want to combine like terms it would be
4r+32
since you add whatever goes together (whole numbers +whole numbers, numbers with variable+ numbers with variable)

Answer:
y= 3 when x= 0
y=3
Step-by-step explanation:
in the problem, there's a patten in the difference of X and Y,
at first, Y is 3 more than X (2 and 5)
then y is 4 more, 5 more, and 6 more.
y goes up by 1 each time
so if Y is 5 when X is 2, then when X is 1 Y is 4
when X is 0 Y is 3
Answer:
2?
Step-by-step explanation:
y is adding by 3 every time...

A psychologist plans an experiment in which subjects draw an object based on a verbal description. For each trial, one person draws, one reads the description, and one records how long it takes to get a successful drawing.
From a group of 8 people, in how many ways can the psychologist select a person to draw, a person to read, and a person to record time?
Answer:
336
Step-by-step explanation:
just took the test
The correct answer is 336.
How many ways can the psychologist select a person to draw, a person to read, and a person to record time?
By using the arrangement calculation formula:
⇒ [tex]A^{3}[/tex][tex]^{8}[/tex]
⇒ 8 × 7 × 6
⇒ 336
The correct answer is 336.
How do you calculate an arrangement?Remember that combinations are a way to calculate the total outcomes of an event where the order of the outcomes does not matter. To calculate combinations, we will use the formula NCR = n! / r! * (n - r)!, where n represents the number of items, and r represents the number of items being chosen at a time.

In the given figure find out the value of x and y ?
Given info:
all sides are equal in the given triangle
It is an equilateral triangle all angles are equal and each angle is equal to 60°Given angles are 3y° and 2x°
→ 3y° = 2x° = 60°
→ 3y° = 60° and 2x° = 60°
→ y° = 60°/3 and x° = 60°/2
→ y° = 20° and x° = 30°
Therefore, x° = 30° and y° = 20°
Answer:-
The values of x = 30° and y = 20°
Key Knowledge:-
→ If all sides are equal in a triangle then it is an equilateral triangle
In an equilateral triangle,
→ all sides are equal.
→ all angles are equal.
→ all angles are equal to 60°

If JM=30 and LM=8, what is KM?
If side JM = 30 and side LM = 8, the length of side KM is equal to 15.49 units.
How to determine the length of side KM?In this exercise, we would assign the variable x to the length of side KM. Based on the information provided about triangle JKM and triangle KML, we can logically deduce the following parameters;
Side JL = [(30 + 8) × x]/2
Side JL = 38x/2
Side JL = 19x.
Since point M is the perpendicular bisector of both triangle JKM and triangle KML, the length of side KM can be calculated as follows;
19x = √[(30² + x²)(x² + 8²)]/2
38x = √[(30² + x²)(x² + 8²)]
By taking the square of both sides, we have:
38²x² = (900 + x²)(x² + 64)
38²x² = 900x² + 57,600 + x⁴ + 64x²
38²x² = 964x² + 57,600 + x⁴
(x² - 240)² = 0
x² = 240
x = √240
x = 15.49 units.

The curve above the graph of a sinusoidal function. It goes through the points (-11,0) and (3,0). Find a sinusoidal function that matches the given graph.if needed you can enter pi=3.1416… as pi in your answer otherwise use at least 3 decimal digits.
F(x)=
Considering the zeros, the graph for the sinusoidal function is:
[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]
The zeros given for the function are: [tex]x = -11, x = 3[/tex].For practicality, we are going to define a sine function, which has a zero at x = 0, so we use shifting.The sine function is given by:
[tex]F(x) = A\sin{Bx}[/tex]
In which:
The amplitude is A.The period is [tex]T = \frac{2\pi}{B}[/tex].In this problem:
We suppose an amplitude of 1, thus [tex]A = 1[/tex].The difference between the zeros is 14, so we use a period of 14, thus [tex]T = 14[/tex], and:[tex]\frac{2\pi}{B} = 14[/tex]
[tex]B = \frac{2\pi}{14}[/tex]
[tex]B = \frac{\pi}{7}[/tex]
Thus:
[tex]F(x) = \sin{\frac{\pi}{7}x}[/tex]
Like this, the zeros are at [tex]x = -14[/tex] and [tex]x = 0[/tex]. We want it at [tex]x = -11, x = 3[/tex], thus, we shift the function 3 units to the right, that is, the function is:
[tex]F(x) = \sin{\frac{\pi}{7}(x-3)}[/tex]
The graph is sketched at the end of this answer, and has the desired behavior, which are points (-11,0) and (3,0).

Well, we're just simplifying the fraction.
(2x^2)(y/4).
(2yx^2)/4.
When powers of the same base are being divided, subtract. The numbers are just plain fractions. 6/3 = 2 and 4/16 = 1/4. x^4/x^2 = x^2 and y^2/y = y.
Edit:
2/4 is 1/2.

Lines l and m are parallel lines cut by transversal n. Angle R is measured by (3x +12)° and angle S is measured by (5x +8)°.
What is the measure of angle s?
A-90°
B-108°
C-72°
D-20*
Answer:
x = 20
Step-by-step explanation:
Lines l and m are parallel so the sum of given angles is = 180
3x + 12 + 5x + 8 = 180 add like terms
8x + 20 = 180 subtract 20 from both sides
8x = 160 divide both sides by 8
x = 20 replace x with 20 in given expression to calculate any measure.
