Answer:
2. 4x³ - 2x² + 4y
3. (2x+3)(2x−5)² (To expand, it would be 8x³ - 28x² - 10x + 75)
Step-by-step explanation:
2.
(4x³ + 2y) - (2x² - 2y)
Find the opposite of 2x² - 2y by finding the opposite of each term.
4x³ + 2y - 2x² + 2y
Add 2y and 2y to get 4y.
4x³ - 2x² + 4y
3.
To simplify this expression, simply multiply 2x - 5 by itself to get (2x + 3)(2x - 5)².
I know this is extra, but I'll expand it out.
(2x + 3)(2x - 5)²
Use binomial theorem (a−b)² =a²−2ab+b² to expand (2x−5) ²
(2x + 3)(4x² - 20x + 25)
Use the distributive property to multiply 2x + 3 by 4x² - 20x + 25.
8x³ - 40x² + 50x + 12x² - 60x + 75
Combine -40x² and 12x² to get -28x².
8x³ - 28x² + 50x - 60x + 75
Combine 50x and -60x to get -10x.
8x³ - 28x² - 10x + 75

Your friends swimming pool is in the shape of a rectangular prism, with a length of 25 feet a width of 8 feet and height of 5 feet. What is the volume of your friends swimming pool?
The volume of a rectangular prism is given as:
Width × Length × Height
Length = 25 feet
Width = 8 feet
Height = 5 feet.
Volume of the rectangular prism(Swimming pool) = 25 feet × 8 feet × 5 feet

Step-by-step explanation:
Simply look at the given x values in the table and whatever x equals in the table, put that value in the equation. For example, y = -x + 7. In the table x value, 0 is given, so the equation will now be y = 0 + 7. So y = 7 and so forth.
To graph, you take the given x value, 0, and the y value you solved for, 7. Your point on the graph would be (0 , 7). Continue repeating these steps till you complete the table and your graph. :)

Equation that could be the equation of parabola with vertex (-3 , 6)
What is parabola?A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point (known as the focus) and from a fixed straight line which is known as the directrix.
Given,
Vertex of parabola (h,k) = (-3, 6)
Vertex-form equation of parabola
y = a(x - h)² + k
y = a(x - -3)² + 6
y = a(x + 3)² + 6
Equation of the parabola should be of form
y = a(x + 3)² + 6
Hence, y = -3(x + 3)² + 6 is the equation that could be the equation of parabola with vertex (-3 , 6)

Mr. Jones has a new car. The manufacturer says that the car should get about 28 miles per gallon in the city. About how many miles can Mr. Jones drive on 11.5 gallons of gas? At 2.89 per gallon, how much would that cost?
Answers
Answer:a) 322 MILES B) 34.391 ( The price per gallon was not given in units ) but if price of I gallon = lets say $2.89, then for 11.5 Gallons will be $34.391
Step-by-step explanation:
a)
M r Jones car needs 28 miles for 1 gallon = 28 MILES= 1 Gallon
Number of miles he can drive withe 11.5 gallons
1 Gallon = 28 miles
11.5 gallons = 11.5 x 28miles = 322 miles
b) IF 1 gallon costs 2.89
11.5 gallons will cost= 11.5 x 2.89= 34.391

solve for x -1/2x + 1/3 > 3/5
Answers
Answer:
x > 8/15
Step-by-step explanation:
x -1/2x + 1/3 > 3/5
Combine like terms
2/2x - 1/2x +1/3 > 3/5
1/2x + 1/3 > 3/5
Subtract 1/3 from each side
1/2x + 1/3 -1/3 > 3/5 -1/3
1/2x > 3/5 -1/3
Get a common denominator
1/2x > 9/15 - 5/15
1/2x > 4/15
Multiply each side by 2
2 * 1/2x > 4/15 * 2
x > 8/15
It is X > 8/15
U is the midpoint of TV. If TU = 6x and TV = 11x + 8, what is TV?
T
6x
V
11x + 8
Simplify your answer and write it as a proper fraction, mixed number, or integer.
Answers
Answer:
96
Step-by-step explanation:
U is the midpoint of TV, so mTU is half of mTV or mTV = 2 * mTU, so
mTV = 2 * mTU
11x + 8 = 2 (6x)
11x + 8 = 12x
8 = x
mTV = 11x + 8 = 11(8) + 8 = 88 + 8 = 96
