4(1-x) + 2x = -3(x+1)
A. -7
B.-3/4
C.-1.4
D.1.4
Pls help
Answer: A
Step-by-step explanation:
4( 1 - x) + 2x = -3(x + 1)
4 - 4x + 2x = -3x - 3 Distribute numbers to paranthesis
4 - 2x = -3x - 3 Add like terms
4 + x = -3 Add 3x to both sides
x = -7 subtract 4 to both sides

Dave and his brother Theo are selling cookies by the pound at the school bake sale. Dave sold 14.84 pounds of cookies and Theo sold 21
pounds of cookies. How many pounds did they sell altogether?
Answer:
35.84
Step-by-step explanation: add together 14.84 and 21 pounds of cookies
Answer:
35.84 pounds
Step-by-step explanation:
You would do 14.84 and 21.00 (because you line up the decimals) then just add how you normally would
The time, t, in seconds, required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters is given by this equation. t=√2d/a
Answer:
720
Step-by-step explanation:
Plato.
t=√2d/a
12=√2d/10
12²=(√2d/10)²
144=2d/10
2d=(144)(10)
d=1440/2
=720
The initial Velocity of that object would be zero.
What is initial velocity?Initial Velocity, denoted as u, is the velocity at time period t = 0. It is the speed at which motion first occurs. When gravity first exerts a force on an object, its initial velocity defines how quickly the object moves.
They are three initial velocity formulas:
(1) If time, acceleration, and final velocity are provided, the initial velocity is articulated as u = v – at
(2) If final velocity, acceleration, and distance are provided we make use of u² = v² – 2 as
(3) If distance, acceleration, and time are provided, the initial velocity is
s = ut + 1/2at²
Where,
Initial velocity = u,
Final Velocity = v,
time taken = t,
distance travelled or displacement = s,
acceleration = a
From the third formula of velocity
s = ut + 1/2at²
If u = 0
then s = 1/2at²
=> at² = 2s
=> t² = 2s/a
=>t = [tex]\sqrt{2\frac{s}{a} }[/tex]
Which is the same as the given equation
therefore, That object's initial velocity would be zero.

One container of fertilizer covers 900 square feet. A property has a rectangular backyard that is 30 feet long and 20
feet wide. The front yard is triangular with a base of 24 feet and a height of 12 feet. What percentage of the container
will be used on the property? Round to the nearest percentage.
Answer:
82.67% of the fertilizer will be used on the property.
Step-by-step explanation:
Area of Plane Figures
The backyard described in the problem has two parts: One with a rectangular shape of 30 feet by 20 feet. The other with a triangular shape with a base of 24 feet and a height of 12 feet.
The area of a rectangle is calculated by:
[tex]A_r=L*W[/tex]
And the area of a triangle is:
[tex]\displaystyle A_t=\frac{B*H}{2}[/tex]
All the backyard will be covered by fertilizer coming from a container with a capacity of 900 square feet.
The total area of the backyard is the sum of the area of the rectangle Ar and the area of the triangle At as follows:
[tex]A_r=30*20=600\ ft^2[/tex]
[tex]\displaystyle A_t=\frac{24*12}{2}=144\ ft^2[/tex]
The total area of the backyard is:
[tex]A=600\ ft^2+144\ ft^2=744\ ft^2[/tex]
To find the percentage of the container, we calculate:
[tex]\displaystyle \frac{744}{900}*100\%=82.67\%[/tex]
82.67% of the fertilizer will be used on the property.
Solve algebraically for all the values of x -2x^5+14x^4-2x^3+14x^2=0
Answer:
0, 7, ± iStep-by-step explanation:
Solving for x
- 2x^5 + 14x^4 - 2x^3 + 14x^2=0x^5 - 7x^4 + x^3 - 7x^2 = 0x^2 ( x^3 - 7x^2 + x - 7) = 0x^2( x^2(x - 7) + (x - 7)) = 0x^2(x^2 + 1)(x - 7) = 0x^2 = 0 ⇒ x = 0x^2 + 1 = 0 ⇒ x^2 = -1 ⇒ x = ± ix - 7 = 0 ⇒ x = 7The solutions to the original equation -2x³ + 14x²- 2x³ + 14x² = 0 are x = 0, -0.391, 0.099, 7.293
To solve the equation algebraically, factor out an "x^2" term from each term:
x²(-2x³ + 14x²- 2x + 14) = 0
Now, we have two factors:
x² = 0
-2x³ + 14x² - 2x + 14 = 0
First, let's solve the first factor, which is a simple quadratic equation:
x² = 0
x = 0
Now, let's solve the second factor by factoring out a common factor of 2:
2(-x³ + 7x² - x + 7) = 0
Now,use the rational root theorem or synthetic division to find the roots of the cubic equation -x³ + 7x² - x + 7 = 0. However, in this case, the equation does not have any rational roots. Therefore, we need to use numerical methods or graphing techniques to find the approximate solutions.
Using numerical methods or graphing, we find that the approximate solutions for the equation -x³ + 7x² - x + 7 = 0 are:
x ≈ -0.391
x ≈ 0.099
x ≈ 7.293

Is the equation 2x +
4 = 5x - 6 a literal equation? Explain.
Answer:
No
Step-by-step explanation:
Say for example that x = 1, so 2 + 4 = 5 - 6 that doesn't work and most likely wont work with any other number.
No, the equation [tex]2x + 4 = 5x - 6[/tex] is not a literal equation.
We have to given equation,
[tex]2x + 4 = 5x - 6[/tex]
What is literal equation?
A literal equation is an equation which consists primarily of letters.
Or we can say that, literal equation are equation with two or more variables.
Now, here given equation is [tex]2x + 4 = 5x - 6[/tex]
Clearly in the above equation only one variable use ( x ), so it is not literal equation.
Another way,
Put x = 1 in above equation we get,
2 + 4 = 5 - 6
clearly it is doesn't work.
So given equation [tex]2x + 4 = 5x - 6[/tex] is not a literal equation.
