We know that Angle BCH and CHJ have the same measures. 

Calculations. 

Solve for variable n 

82+30=3n+7

3n=105

n=35

6x2-30=0
agasfer [191]

The quadratic form is ax^2 + bx + c

The given equation is 6x^2 -30 = 0

a = 6 because it is with x^2.

There is no x term in the equation so b is 0

c is the numerical term with no variable so c = -30

a = 6

b = 0

c =-30

How do you work out 8x+3=8×+27
Alekssandra [29.7K]

Answer:

No solution

Step-by-step explanation:

8x + 8 = 8x + 27

You then cancel out the 8s. 8 - 8 = 0

Which leaves you with 8 = 27...

Since this is an untrue statement, the answer would be no solution, unless you typed it wrong.
