Answer:

x = 8

Step-by-step explanation:

rearrange:

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

6*x-18-(30)=0

STEP 1:

Pulling out like terms

Pull out like factors :

6x - 48 = 6 • (x - 8)

STEP 2:

Equations that are never true:

Solve: 6=0

This equation has no solution.

Solving a Single Variable Equation:

Solve : x-8 = 0

Add 8 to both sides of the equation :

x = 8

Factor completely:<br><br> <img src="https://tex.z-dn.net/?f=3x%5E3%2B21x%5E2%2B36x" id="TexFormula1" title="3x^3+21x^2+36x" alt

To factor, you can first treat it like a single bracket and find the common factor. In this case, the common factor is 3x, so you get
3x(x² + 7x + 12)
Now you can factor the bracket normally, by finding factors of 12 that add up to make 7. The factors would be 3 and 4, so the bracket becomes (x + 3)(x + 4).
This leaves your final answer as
3x(x + 3)(x + 4)

I hope this helps!

Answer:

Step-by-step explanation:

Perimeter of Square = 40 cm

4*side = 40

side = 40/4

side = 10 cm

Area of shaded region= Area of square - [Area of triangle 1 + Area of triangle 2]

$=[side*side]-[\frac{1}{2}*b*h+\frac{1}{2}*b*h]\\\\=[10*10]-[\frac{1}2}*3*10+\frac{1}{2}*10*6]\\\\=100-[3*5+5*6]\\\\=100-[15+30]\\\\=100-45\\\\=55cm^{2}\\$
