Find the product of the monomial and the polynomial: 4x^3y^3*(3x^3-7xy^2+2xy-y)
Answer: 12x^6y^3-28x^4y^5+8x^4y^4-4x^3y^4
Step-by-step explanation:
The requierd product of 4x³y³ and (3x³-7xy²+2xy-y) is:
12x⁶y³ - 28x⁴y⁵ + 8x⁴y⁴ - 4x³y⁴
What is a polynomial?A polynomial is defined as a mathematical expression that has a minimum of two terms containing variables or numbers. A polynomial can have more than one term.
The monomial and the polynomial are given in the question, as follows:
4x³y³ × (3x³-7xy²+2xy-y)
To find the product of the monomial 4x³y³ and the polynomial (3x³-7xy²+2xy-y), we need to multiply each term in the polynomial by the monomial and then add the results.
(4x³y³) × (3x³) = 12x⁶y³
(4x³y³) × (-7xy²) = -28x⁴y⁵
(4x³y³) × (2xy) = 8x⁴y⁴
(4x³y³) × (-y) = -4x³y⁴
⇒ 12x⁶y³ - 28x⁴y⁵ + 8x⁴y⁴ - 4x³y⁴
Therefore, the product of 4x³y³ and (3x³-7xy²+2xy-y) is:
12x⁶y³ - 28x⁴y⁵ + 8x⁴y⁴ - 4x³y⁴

Answer:
D) a = b= 2√2
Step-by-step explanation:
The hypotenuse of an isosceles right triangle is √2 times the side length. This means you have ...
a√2 = 4
a = 4/√2 = 4(√2)/2 = 2√2
Of course, the side lengths are the same (as all answer choices show you). The correct choice is ...
a = 2√2, b = 2√2
To rent a certain meeting room, a college charges a reservation fee of $36 and an additional fee of $8.80 per hour. The history club wants to spend less than
$106.40 on renting the meeting room
What are the possible amounts of time for which they could rent the meeting room?
Use t for the number of hours the meeting room is rented, and solve your inequality for t.
Answer:
the maximum hours that they can rent it for is 8
Step-by-step explanation:
36 + 8.8t < 106.4
8.8t < 70.4
t < 8
Plzzzzzz help! What is the area of figure A?
Answer:
A=24m^2
Step-by-step explanation:
to find the area of this figure you can approach it multiple ways, the simplest way is to split it into two rectangles
respectively one 6m by 3m and another 3m by 2m
find the areas of each rectangle and add them both to get the total area of the figure
(6m*3m)+(3m*2m)=(18+6)m^2=24m^2

h (x) = x + 4; Find h (x – 3)
Answer:
The answer is option 2.
Step-by-step explanation:
You have to substitute the expressions into x :
h(x) = x + 4
h(x - 3) = (x - 3) + 4
h(x - 3) = x - 3 + 4
h(x - 3) = x + 1

Jacqui is selling scented candles as a fundraiser for a school field trip. Each cinnamon candle sells for $3.50 and each chocolate candle sells for $2.50. She raised a total of $94.50 for the trip. The number of chocolate candles that Jacqui sold is three less than twice the number of cinnamon candles. Let c represent the number of chocolate candles and let m represent the number of cinnamon candles. How many chocolate candles did Jacqui sell?
Answer:
Number of cinammon = 12
Number of chocolate = 21
Step-by-step explanation:
Given that:
Cost of Cinnamon candle , c = $3.50
Cost of chocolate candle , d = $2.50
Total amount raised, T = $94.50
d = 2c - 3
Total amount = (cost of Cinnamon * number sold) + (cost of chocolate * number sold)
94.50 = (3.50 * c) + (2.50 * (2c-3))
94.50 = 3.50c + 5c - 7.5
94.50 = 8.50c - 7.5
94.50 + 7.5 = 8.50c
102 = 8.50c
c = 102 / 8.50
c = 12
d = 2c - 3
d = 2(12) - 3
d = 24 - 3
d = 21
Answer:
D.) 21

Answer:
24x+48
Step-by-step explanation:
(3x+6)(8)
=8(3x+6)
=(8*3x)+(8*6)
=24x+48
Answer: 24x + 48
Step-by-step explanation:
The formula to find the are of a rectangle is A=LW. A being the total area, W being the width, or the value on the bottom (8), and L being length how tall the object is (3x+6).
First you must replace L and W, for their given values.
A= (L) (W)
A= (3x+6) (8)
Then, simply simplify by multiplying 3x+6 by 8
You would end up getting 24x + 48

Line I is parallel to line m. If the measure of <6 is 75, what is the measure of <3
Answer:
m∠3 = 105°
Step-by-step explanation:
Line 'l' is parallel to line 'm' and a transversal is intersecting these parallel lines at two distinct points.
m∠3 + m∠6 = 180° [Consecutive interior angles]
Since, ∠6 = 75° [Given]
m∠3 + 75° = 180°
m∠3 = 180 - 75
= 105°
Therefore, measure of ∠3 is 105°.
In the given diagram, the measure of ∠3 is 105°
From the question,
We are to determine the measure of ∠3
In the diagram, ∠3 and ∠6 are consecutive interior angles
NOTE:
If two parallel lines are cut by a transversal, then the pairs of consecutive interior angles formed are supplementary
That is,
∠3 + ∠6 = 180°
From the given information,
∠6 = 75°
Then, we can write that
∠3 + 75° = 180°
∠3 = 180° - 75°
∠3 = 105°
Hence, the measure of ∠3 is 105°
