Answer:
-3x^2
Step-by-step explanation:
We must do the 'work' inside the parentheses first:
(3x squared) works out to 3x^2
after which we preface this result with the ' - ' sign: -3x^2
Note: if we write ONLY 3x squared the correct interpretation is 3x^2. But if we write (3x) squared, the correct interpretation is 9x^2. Double check the original problem, please, or (better yet) share an image of the original problem.

drag each expression to show whether it is equivalent to 3 time times 9 or to 2x3x9
Answer:
The answers to your questions are given below
Step-by-step explanation:
A. 3 × 9 = 27
B. 2 × 3 × 9 = 54
Next, we shall determine which option will give the same result obtained above.
9 × 3 = 27
9 × 3 × 2 = 54
3 × (4 + 5) = 3 × 9 = 27
(2 × 3) × 9 = 6 × 9 = 54
Therefore,
3 × 9 = 27
9 × 3 = 27
3 × (4 + 5) = 27
2 × 3 × 9 = 54
9 × 3 × 2 = 54
(2 × 3) × 9 = 54
SUMMARY
3 × 9 >>>>>>>>> 2 × 3 × 9
9 × 3 >>>>>>>>> 9 × 3 × 2
3 × (4 + 5) >>>>> (2 × 3) × 9

Confused bab in need ☹️
Answer:
25 in^2
Step-by-step explanation:
So the area of a triangle is (Base * Height) / 2. The base, which is where the triangle "sits" is 10 in. The height is 5 in.
With this, these numbers can both be plugged in to get the answer:
(10 * 5) / 2
50/2
25 in^2
It is squared after the units since it is the area.

Given:
The dimensions of the square photo are 12'' × 12''.
The frame is 2 inches wider than the photo in both length and width.
To find:
The perimeter of the frame.
Solution:
We have,
Length of the photo = 12 inches
Width of the photo = 12 inches
The frame is 2 inches wider than the photo in both length and width. So,
Length of the frame = 12+2 inches
= 14 inches
Width of the frame = 12 inches
= 14 inches
The perimeter of a square is:
[tex]P=4a[/tex]
Where, a is the side length.
Now, the perimeter of the square frame with side 14 inches is:
[tex]P=4(14)[/tex]
[tex]P=56[/tex]
Therefore, the perimeter of the square frame is 56 inches, Hence, option A is correct.
I NEED HELP!!! ASAP!!
Answer:
1)
Perimeter=24 inches
Area= around 43.46 inches
Step-by-step explanation:
1) Perimeter = 3in * number of sides
Perimeter = 3*8 = 24
Area= 2(1+ square root of 2) length of one side squared
=42.46
2)
Perimeter = 24
Area= 43.46 inches squared- 3inches
3)
Perimeter = 24
Area= 43.46- triangle area
triangle area = height x base /2
Height = 3, we can compare it.
Base = 3
Triangle = 9/2
Area = 43.46- 4.5
Area =38.96
Can't see 4 and 5 for some reason
6)
Perimeter = 30
Area = 61.94

At a football stadium, 4% of the fans in attendance were teenagers. If there were 80
teenagers at the football stadium, what was the total number of people at the
stadium?
Answer:
2000 people
Step-by-step explanation:
4%= 80
2%=40
1%=20
100%= 2000 people
Hope this helped! :)
Answer:
2000 people
Step-by-step explanation:
80:4%
y:100%
[tex]\frac{80}{y} =\frac{4}{100}[/tex]
y × 4 = 80 × 100
4y = 8000
4y ÷ 4 = 8000 ÷ 4
y = 2000

SAS because its is side angle side for both of them
Answer:
SSS (Side-Side-Side)
Step-by-step explanation:
It is given that PS ≅ RQ. Shown by congruency symbols, PR ≅ RQ. Lastly, QR ≅ QR due to the reflexive property.
Due to all three sides between the two triangles being congruent, you can conclude that they are congruent by SSS, or Side-Side-Side.

Before rock climbing, Michelle wants to know how
high she will climb. She places a mirror on the
ground and walks backward until she can see the
top of the cliff in the mirror. She drew a sketch of
the situation. What is the height of the cliff?
Answer:
22 feets
Step-by-step explanation:
From the diagram attached :
We have two similar triangles which can be related proportionally :
Hence ;
Mitchell's height / distance from mirror = cliff height / cliff distance
Michelle's height = 5.5
Michell's distance from mirror = 4
Cliff height = h
Cliff distance from mirror = 16
We have ;
5.5 / 4 = h / 16
Cross multiply :
4 * h = 5.5 * 16
h = 88 / 4
h = 22 feets

Answer:
$28.20
Step-by-step explanation:
11 bumper stickers = $10.34
per sticker = $0.94
30 bumper stickers = 30*0.94
=28.20
30 bumper stickers = $28.20
Answer:
$28.20
Step-by-step explanation:
First, find out how much each bumper sticker costs.
Assuming that the cost of each bumper sticker is the same, the following equation represents how much one number sticker costs.
11x = 10.34
Solve for x [divide both sides by 11]
x = 0.94
So, one bumper sticker costs $0.94
Now, find out how many 30 bumper sticker costs.
The following equation represents how much 30 stickers cost.
30x = y
X represents the cost of one sticker and y represents the cost of 30 stickers.
We already know the value of x [one bumper sticker's cost] which is $0.94, so subsitute that in for x.
30[0.94] = y
28.2 = y
So, 30 bumper stickers cost $28.20.

Maryanne went to lunch with a friend. The bill was $35.60 before tax. Sales tax rate is 7.25%, and she
decided to leave a 15% tip. What was the final total of her lunch bill?
Answer:
$43.91
Step-by-step explanation:
Calculating Total Cost. Multiply the cost of an item or service by the sales tax in order to find out the total cost. The equation looks like this: Item or service cost x sales tax (in decimal form) = total sales tax. Add the total sales tax to the Item or service cost to get your total cost.
$35.60 + $2.58 (tax) = $38.18
$38.18+ $5.73 (tip at 15%) = $43.91 total

Answer:
Step-by-step explanation:
Hemisphere Formula: ( 2 / 3 ) πR = V
Substitution: ( 2 / 3 ) 3.14 * 6 = 12.56
Cylinder Formula: πR^2 * H = V
Substitution: 3.14 * 6^2 * 15 = 1695.6
