Expand and simplify (x+2)(x+4)(x+6)

Mathematics
1 answer:
Deffense [45]2 years ago
5 0

Answer:

Multiply the first two binomials: (x+2) & (x+4) using the FOIL method (First, Outer, Inner & Last).

(x+2)(x+4) = x^² + 4x + 2x + 8 = x^² + 6x + 8

Then we multiply the trinomial that we got from the first stage and multiply that by the remaining binomial:

(x^² + 6x + 8) (x + 4)

= x^³ + 4x^² + 6x^² + 24x + 8x + 32

Collect the like terms together to give you:

x^³ + 10x^² + 32x + 32

Three boys share R2100 in ratio 3:5:7 calculate how much each boy will get​
aleksandrvk [35]

The amount each boy receives from the R2100 is R420, R700 and R980 respectively

<h3>How to find ratio</h3>

Total amount = R2100

Ratio = 3 : 5 : 7

Total ratio = 3 + 5 + 7

= 15

First boy = 3/15 × 2100

= 0.2 × 2100

= R420

Second boy = 5/15 × 2100

= 0.33333333333333 × 2100

= R700

Third boy = 7/15 × 2100

= 0.46666666666666 × 2100

= R980

Which graph shows the solution to the system of linear inequalities below?
hodyreva [135]

Answer:

Option B

The solution in the attached figure

Step-by-step explanation:

we have

<em>Inequality A</em>

y > -\frac{1}{3}x+1

we know that

The solution of the inequality A is the shaded area above the dashed line

The equation of the dashed line is y=-\frac{1}{3}x+1

The slope of the dashed line is negative m=-\frac{1}{3}

<em>Inequality B</em>

y > 2x-1

we know that

The solution of the inequality B is the shaded area above the dashed line

The equation of the dashed line is y=2x-1

The slope of the dashed line is positive m=2

therefore

The solution in the attached figure

The measurement of a central angle is θ=240 degrees. Find the measurement of θ in radians.
Mazyrski [523]

Answer:

4.189 radians

Step-by-step explanation:

Given data

θ=240 degrees

Let us convert from  degrees to radians

Angle in Radian= Angle in degree* π/180

Substitute

Angle in Radian= 240* π/180

Angle in Radian= 4* π/3

Angle in Radian= 4* 3.142/3

Angle in Radian=12.568/3

Angle in Radian=4.189 radians
