Step-by-step explanation:

6 {x}^{2}  - 30  = 0 \\  \therefore \: 6( {x}^{2}  - 5) = 0 \\ \therefore \: {x}^{2}  - 5 = 0 \\ \therefore \: {x}^{2}  =  5\\ \therefore \: x = \pm \:  \sqrt{5}\\  \\

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

Complementary angles have measures (4x)° and (5x−27)°. find the measure of the larger angle.
Luda [366]

Answer:

4x=90

X=90÷4

X=22.5

5x-27=90

5x=90+27

5x=117

X=117÷5

X=23.4

So 23.4 is a larger angle
