Answer:

(x+4)(x-3)

Step-by-step explanation:

You have to find factors of 12 that also add together to make 1 (coefficient of x is 1) and factors that multiply together to make x^2.

4×-3=-12

4+-3=1

x×x=x^2

Answer:

Ella sold 100 boxes, and Sarah sold 60 boxes

Step-by-step explanation:

Variables:

Let s be sarah

Let e be ella

Equations:

3e = 5s

s + e = 160 ⇒ s = 160 - e

Work:

3e = 5(160 - e)

3e = 800 - 5e

+5e          +5e

8e = 800

e = 100

Ella sold 100 boxes of chocolates.

3(100) = 5s

5s = 300

*divide both sides of the equal sign by 5

s = 60

Sarah sold 60 boxes

Answer:

11

Step-by-step explanation:

While I square, all the sides of square are the same side, right on the same length. So therefore, um, one side of the square must be equal to well 44 divided by four because they're all the same length. So therefore, one side of the square is just 44 divided by four, which is 11.

The rate of change of the depth of water in the tank when the tank is half

filled can be found using chain rule of differentiation.

When the tank is half filled, the depth of the water is changing at  1.213 ×

10⁻² ft.³/hour.

Reasons:

The given parameter are;

Height of the conical tank, h = 8 feet

Diameter of the conical tank, d = 10 feet

Rate at which water is being pumped into the tank, = 3/5 ft.³/hr.

Required:

The rate at which the depth of the water in the tank is changing when the

tank is half full.

Solution:

The radius of the tank, r = d ÷ 2

∴ r = 10 ft. ÷ 2 = 5 ft.

Using similar triangles, we have;

[tex]\dfrac{r}{h} = \dfrac{5}{8}[/tex]

The volume of the tank is therefore;

[tex]V = \mathbf{\dfrac{1}{3} \cdot \pi \cdot r^2 \cdot h}[/tex]

[tex]r = \dfrac{5}{8} \times h[/tex]

Therefore;

[tex]V = \dfrac{1}{3} \cdot \pi \cdot \left( \dfrac{5}{8} \times h\right)^2 \cdot h = \dfrac{25 \cdot h^3 \cdot \pi}{192}[/tex]

By chain rule of differentiation, we have;

[tex]\dfrac{dV}{dt} = \mathbf{\dfrac{dV}{dh} \cdot \dfrac{dh}{dt}}[/tex]

[tex]\dfrac{dV}{dh}=\dfrac{d}{h} \left( \dfrac{25 \cdot h^3 \cdot \pi}{192} \right) = \mathbf{\dfrac{25 \cdot h^2 \cdot \pi}{64}}[/tex]

[tex]\dfrac{dV}{dt} = \dfrac{3}{5} \ ft.^3/hour[/tex]

Which gives;

[tex]\dfrac{3}{5} = \mathbf{\dfrac{25 \cdot h^2 \cdot \pi}{64} \times \dfrac{dh}{dt}}[/tex]

When the tank is half filled, we have;

[tex]V_{1/2} = \dfrac{1}{2} \times \dfrac{1}{3} \times \pi \times 5^2 \times 8 =\mathbf{ \dfrac{25 \cdot h^3 \cdot \pi}{ 192}}[/tex]

Solving gives;

h³ = 256

h = ∛256

[tex]\dfrac{3}{5} \times \dfrac{64}{25 \cdot h^2 \cdot \pi} = \dfrac{dh}{dt}[/tex]

Which gives;

[tex]\dfrac{dh}{dt} = \dfrac{3}{5} \times \dfrac{64}{25 \cdot (\sqrt[3]{256}) ^2 \cdot \pi} \approx \mathbf{1.213\times 10^{-2}}[/tex]

When the tank is half filled, the depth of the water is changing at  1.213 × 10⁻² ft.³/hour.

Answer:

20m-60 = 280

Step-by-step explanation:

1. Start off defineing a variable, let’s call it m for months.

2. We know that she saves 20$ every month, so we can just divide the total to find the number of months. But, she withdrew $60. We can add those back to get the total she saved. So we have

280 + 60 = 340

Then we can divide by 20:

340/20 = 17.

So the equation would be

20m - 60 = 280.

Answer:

4r -2s+3

Step-by-step explanation:

Looks like you're given

x cos(y/x) (y dx + x dy) = y sin(y/x) (x dy - y dx)

Like with your other equation, multiply by 1/x² on both sides:

cos(y/x) (y/x dx + dy) = y/x sin(y/x) (dy - y/x dx)

Then substitute z = y/x again, so y = xz and dy = x dz + z dx. You end up with a separable equation.

cos(z) (z dx + x dz + z dx) = z sin(z) (x dz + z dx - z dx)

cos(z) (2z dx + x dz) = xz sin(z) dz

2z cos(z) dx = x (z sin(z) - cos(z)) dz

(z sin(z) - cos(z)) / (z cos(z)) dz = 2/x dx

(tan(z) - 1/z) dz = 2/x dx

Integrate both sides:

∫(tan(z) - 1/z) dz = ∫ 2/x dx

-ln|cos(z)| - ln|z| = 2 ln|x| + C

ln|cos(z)| + ln|z| = -2 ln|x| + C

ln|z cos(z)| = ln(1/x²) + C

z cos(z) = C/x²

Solve in terms of y :

(y/x) cos(y/x) = C/x²

y cos(y/x) = C/x

The solution of the given equation 2x + 5 = 3x + 2 is 3.

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

The equation must be constrained with some constraints.

As per the given equation,

2x + 5 = 3x + 2

2x + 5 - 2x = 3x + 2 - 2x

2x - 2x + 5 = 3x  - 2x + 2

5 = x + 2

5 - 2 = x + 2 - 2

3 = x

Hence "The solution of the given equation 2x + 5 = 3x + 2 is 3".
