What is the factorization of 2x + 5x + 3?
Answer:
(2x+3)(x+1)
Step-by-step explanation:
A P E X
The factorization of the polynomial 2x² + 5x + 3 is (2x + 3)(x + 1).
What is Polynomial?Polynomial is an expression consisting of indeterminates and coefficients, that involves only the operations of addition, subtraction, multiplication, and positive-integer powers of variables
To factorize 2x² + 5x + 3, we need to find two binomials in the form of (ax + b) and (cx + d) such that their product equals the given expression.
Firstly Multiply the coefficient of the first term (2) by the constant term (3) to get 6.
The two factors of 6 that add up to the coefficient of the middle term (5). In this case, the factors are 2 and 3.
Now Rewrite the middle term using the two factors found in the previous step. We have:
2x² + 2x + 3x + 3
We can factorize the first two terms by taking out 2x as a common factor and the last two terms by taking out 3 as a common factor. We get:
2x(x + 1) + 3(x + 1)
(2x + 3)(x + 1)
Therefore, the factorization of 2x² + 5x + 3 is (2x + 3)(x + 1).

No she should not purchase it.
Step-by-step explanation:
because the width that comes out to be is equal to area divided by length
[tex] \frac{46 \times 7}{8} \times \frac{2}{7} = 11.5[/tex]
which comes out to be 11.5 which is greater than 6.

Is y=-x+5 proportional
Answer:
yes
Step-by-step explanation:
I'm not entirely sure what your question is, but x is directly proportional to y, meaning as as x increases at a constant rate, y also increases at a constant rate.

At the shorter waterfall, water falls uninterrupted for 1552 feet before entering the river below. The height h above the river in feet of water going over the edge of the waterfall is modeled by h\left(t\right)=-16t^2+1552h(t)=−16t^2+1552, where is the time in seconds after the initial fall. Estimate the time it takes for the water to reach the river. Round your answer to the nearest tenth.
Answer:
9.9sStep-by-step explanation:
First note that the river is on the ground level. The height of the river at the ground level is 0
Given the the height h above the river in feet of water going over the edge of the waterfall is modeled by h(t)=-16t^2+1552
When h = 0
0 = -16t^2+1552
16t^2 = 1552
t² = 1552/16
t² = 97
t = √97
t = 9.9secs
Hence the time it takes is 9.9secs to the nearest tenth

a second sheet of paper is half as long and half as wide as the one described in part a. by what factor is its area less than the area found in part a?
The area of the second paper sheet of paper is 1/4 less than the other area
Information about the problem:
Sheet of paper figure = rectangleLength = 1/2* L₁Width = 1/2 * W₁The formula and procedure to solve this geometry exercise is:
A(rectangle) = length * width
A(rectangle) = 1/2 L₁ * 1/2 W₁
A(rectangle) = 1/4 (L₁*W₁)
Hence, the factor of the second sheet of paper less than the first area is 1/4
What is the area?Is the measure of the space occupied by a body bounded by an environment called perimeter, the same is expressed in units of squared side. Example: ft^2, m^2

Hunter owns a food truck that sells tacos and burritos. He sells each taco for $3.25 and each burrito for $6.50. Yesterday Hunter made a total of $520 in revenue from selling a total of 120 tacos and burritos. Graphically solve a system of equations in order to determine the number of tacos sold, x,x, and the number of burritos sold, yy.
what are the two equations?
Answer:
x=80 y=40
Step-by-step explanation:
Write an equation with variables on each side of the equal sign, at
least one fractional coefficient, and a solution of -6.
Graph the function f(x) = x3 – 10x2 + 28x – 24 Then, write a
written description of the graph that includes all key characteristics below.
- Type of polynomial function and degree
- Domain & Range
- End behavior
- Intervals of Increasing/Decreasing
- Intervals of Positive/Negative
- Turning points (including whether it's a relative max or relative min)
- Zeros and their multiplicity (and the effect of the multiplicity on the graph)
- Cubic Function | 3-degree
- Domain & Range | Domain and Range both are all set of Real Numbers.
- End Behavior | When x approaches positive infinity, f(x) approaches positive infinity as well. When x approaches negative infinity, f(x) approaches negative infinity too.
- Intervals of Increasing/Decreasing | Increases at (-∞, 2) U (6,∞) and Decreases at (2,14/3) aka 2 < x < 14/3
- Intervals of Positive/Negative
Positive when x > 6 or (6,+∞)
Negative when 2 < x < 6 and x < 2 or (2,6) U (-∞,2)
- Turning Points are (2,0) and (14/3, -256/27)
- Zeros and Multiplicity | Factoring the polynomial as we get (x-2)(x-2)(x-6). Therefore, the zeros are multiplication of 2 and 6.
Multiplicity will affect the graph for x-axis. When the multiplicity kicks in, the graph will turn either decreasing on increasing on x-axis immediately.
Also I was plotting the graph so It might take too long.

This week, the art museum gave away 1,200 tickets to the Greco exhibit, which was 150 percent as many tickets as it gave away last week. Martin is trying to figure out how many tickets the museum gave away last week. His work is shown below.
Step 1: StartFraction part Over whole EndFraction = StartFraction 150 Over 100 EndFraction = StartFraction question mark Over 1200 EndFraction
Step 2: 100 times 12 = 1200
Step 3: 150 times 12 = 1800
In what step did Martin make a mistake, if any?
Step 1: Martin should have written his ratio as StartFraction 1200 Over question mark EndFraction.
Step 2: Martin should have divided 1200 by 8.
Step 3: Martin should have added 1200 and 150.
Martin did not make any mistakes.

Round your answer to the nearest hundredths. (Use π = 3.14.) Note that all measurements are in centimeters and images are not drawn to scale. (1 point)
A cylinder with width 5.5 and height unknown is labeled glass 1, and a cone with height 6.8 and width 5.2 is labeled glass 2.
Group of answer choices
4.82 centimeters
3.03 centimeters
7.47 centimeters
5.64 centimeters
the correct answer is 3.03 cm !!!!!!
Solve for x
(4x - 1) °
(3x - 8)°
(3x-8) + (4x-1) = 180
7x-9=180
7x=189
x=189/7
x = 27
(3(27)-8) = 73
(4(27)-1) = 107
