Answer:

2x^2+7x-16

Step-by-step explanation:

x(3x-1)-(x-4)^2

Use distributive: x(3x-1)=3x^2-x

Use square of a binomial formula : (a-b)^2=a^2-2ab+b^2

(x-4)^2=x^2-8x+16

3x^2-x-(x^2-8x+16)=3x^2-x-x^2+8x-16=2x^2+7x-16

The answer is 2x^2+7x-16

Hope this helps :)

Have a nice day!

What is the equation of a horizontal line that has a y-intercept of 3.5?
beks73 [17]
First, recall that the equation of a line is

y = mx+b

where 

m = slope
b = y-int

The key to this question is the details :

Horizontal line ---> This tells you that your slope is 0

y-int = 3.5 -----> In the equation above, b=3.5

Therefore,

y = 0x + 3.5
y = 0 + 3.5
y = 3.5

At a greengrocer, two bananas and one apple cost ?1.16 and one banana and one apple cost ?0.71. How much does one apple cost?
Blababa [14]

Answer

Find out the how much does one apple cost .

To prove

Let us assume that the number of bananas be x .

Let us assume that the number of apples be y .

As given

At a greengrocer, two bananas and one apple cost $1.16 .

Than the equation becomes

2x + y = 1.16

one banana and one apple cost $0.71.

Than the equation becomes

x + y = 0.71

Subtracting x + y = 0.71 from 2x + y = 1.16

2x - x + y - y = 1.16 - 0.71

x = 0.45

Put in the equation x + y = 0.71

0.45 + y = 0.71

y = 0.71 - 0.45

y = $0.26

Therefore the cost of the one apple is  $0.26 .

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
