Can anyone solve 84=4(1 - 4g) step by step?
lyudmila [28]

Answer:

g= -5

Step-by-step explanation:

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

                    84-(4*(1-4*g))=0

 84 -  4 • (1 - 4g)  = 0

3.1     Pull out like factors :

  16g + 80  =   16 • (g + 5)

16 • (g + 5)  = 0

4.1      Solve :    16   =  0

This equation has no solution.

A a non-zero constant never equals zero.

4.2      Solve  :    g+5 = 0  

Subtract  5  from both sides of the equation :  

                     g = -5

I hope it helps you and if you want you can give me a brainly crown only if you want

Which function is a quadratic function? c(x) = 6x + 3x3 d(x) = x – 8x4 p(x) = –5x – x2 k(x) = 2x2 + 9x4
Citrus2011 [14]
Easy
quadratic means 2nd degree

means highest power of exponent is 2
so like x^2

first one
we have 3x^3, that is 3rd degree,nope

2nd one
we have 8x^4, nope, that is 4th degree

3rd one
we have -x^2, yep

4th one, we have 9x^4, that is 4th degree

answer is 3rd one or p(x)=-5x-x^2
