Answer:
2(2x-4)
Step-by-step explanation:
area is side times side and all the sides of a square are the same. SO, 2 times 2x-4 is your answer
The expression that represents the area of the square is 4x² - 16x + 16.
What is a square?A square is a two-dimensional figure that has four sides and all four sides are equal.
The area of a square is side²
We have,
The area of a square can be calculated by multiplying its side length by itself.
Therefore, the area of a square with a side length of 2x - 4 can be calculated as.
Area = (2x - 4) x (2x - 4)
Expanding the expression.
Area = 4x² - 16x + 16
Therefore,
The expression that represents the area of the square is 4x² - 16x + 16.

A building in the shape of a cube has a width of 30 ft., a length of 30 ft., and a height of 30 ft. An architect wants to build a scale model of the building that is 10% smaller in volume. What is the height of the new building?
Answer:
Step-by-step explanation:
The height of the scale model is 13.92 feet. (Rounding to the nearest hundredth).
Step-by-step explanation:
These are the measurements of the real building:
Height = 30 feet
Width = 30 feet
Length = 30 feet
Volume of the real building = 30 * 30 * 30 = 27,000 cubic feet
These are the measurements of the scale model:
Volume of the scale model = 10% of 27,000 cubic feet
Volume of the scale model = 0.1 * 27,000 = 2,700 cubic feet
Height = ∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)
Width = ∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)
Length =∛ 2,700 = 13.92 feet (Rounding to nearest hundredth)
The height of the scale model is 13.92 feet.
Answer:
28,96 ft (round to the nearest hundreds)
Step-by-step explanation:
1) find the volume of the first cube
V = side^3 = 30^3 = 27000 ft^3
2) find the 10% of 27000
27000 / 0,1 = 2700
3) find the volume of the second cube
V = 27000- 2700 = 24300 ft^3
4) find the height
height = ∛24300 = 28,96 ft (round to the nearest hundreds)

Find the length of AB
Answer:
35.6 units
Step-by-step explanation:
By intersecting chords theorem:
10*x = 16*16
10x = 256
x = 256/10
x = 25.6
AB = 10 + x
AB = 10 + 25.6
AB = 35.6

A
up
B

Answer:
D. right
Step-by-step explanation:
f(x) = 4*2^x
g(x) = 4*2^(x-3)
g(x) = f(x - 3), so g(x) is shifted 3 units right.
find the value of x (160 digrees (10x + 50) degrees
Answer:
x is 5
Step-by-step explanation:
Answer: Not entirely sure if I understand the question, but if I do, then x = 11
Step-by-step explanation:
We know 10x + 50 = 160
We can start by removing 50 from both sides. Then we get: 10x = 110
Then we can divide both sides by 10 and get:
x = 11

When will a quadratic equation have two different real roots?
a) when a discriminant is positive
b) when a discriminant is negative
c) when a discriminant is zero
Answer:
A
Step-by-step explanation:
When a discriminant is positive it has two distinct roots. When a discriminant is negative it has no real roots. When a discriminant is zero it has two roots that are the same so that counts as one root.

The total mass of Fatin and Hanim is 68 kg. Fatin is 6 kg lighter than Hanim. Find their respective masses.
Answer:
Hatim=37kg, Fatin=31
Step-by-step explanation:
Hatim=x, Fatin=x-x
x+x-6=68
add 6 to both sides
x+x=74
2x=74
divide both sides by 2
x=37
put in 37 fo the values determined earlier
Hatim=37, Fatin=37-6
Hatim=37, Fatin=31
check by plugging in the values
37+31=68 (or 37+37-6=68, either one works)

What is division?The division in mathematics is one kind of operation. In this process, we split the expressions or numbers into the same number of parts.
Given:
We have the unit rate of 30 meters per second.
A) 90 meters in 5 seconds.
The unit rate = 90/5 meters per second.
The unit rate = 18 meters per second.
B) 90 meters in 3 seconds.
The unit rate = 30 meters per second.
C) 120 meters in 6 seconds.
The unit rate = 20 meters per second.
D) 150 meters in 5 seconds.
The unit rate = 30 meters per second.
E) 240 meters in 6 seconds.
The unit rate = 40 meters per second.
Therefore, B and D have the unit rate of 30 meter per second.

Answer:
A
Step-by-step explanation:
Flat fee is $20 [initial cost]
Each bucket of ball is $5.75
b is the number of buckets and c is the total cost
To get total cost, we add the flat fee with the bucket fee. Bucket fee is $5.75 multiplied by the number of buckets, which is b.
So, we have:
cost = $20 + $5.75b

Which account has the highest annual interest rate?
A. Account 1: Interest is compounded daily at a rate of 5.25%.
B. Account 2: Interest is compounded monthly at a rate of 5.40%.
C. Account 3: Interest is compounded quarterly at a rate of 5.50%.
D. Account 4: Interest is compounded annually at a rate of 5.55%.
Answer:
A
Step-by-step explanation:
So we know that B talks of monthly, which is about 30 times less than the daily interest(A).
Next we have quarterly(C), which is every three months. This would be 3 times longer than B, and over 90 times longer than daily(A).
Finally we have D, which is anual interest. Anual is only once a year, which is four times longer than C, 12 times longer than B, and over 360 times longer than A.
Answer:
A is the highest interest rate.
