<h2>Required Answer:</h2>

Given pair of expression :

$\longrightarrow \sf {(4x -7) \: and \: (7-4x) }$

Solution :

Firstly put the sign of addition (+) at the place of and.

$\longrightarrow \sf {(4x -7) + (7-4x) }$

Now, remove the brackets.

$\longrightarrow \sf {4x -7 + 7-4x }$

Group like terms. Here, 4x and -4x ; -7 and +7 are like terms.

$\longrightarrow \sf {\cancel{4x -4x} \cancel{ -7 + 7}}$

$\implies \sf \red {0 }$

So, the answer is 0.

4y-70=12y+2 Solve????

Lady_Fox [76]

Simplifying 4y + -70 = 12y + 2

Add -12y to each side of the equation. -70 + 4y + -12y = 2 + 12y + -12y

Add 70 to each side of the equation. -70 + 70 + -8y = 2 + 70

Divide each side by -8.

So y = -9 is your answer.

Hope I Helped!!!

Which statement about g(x)=x^2-576 is true

Ipatiy [6.2K]

Answer:

c. the zeros, -24 and 24, can be found when 0= (x+24)(x-24).

Step-by-step explanation:

The given function is

$g(x)=x^2-576$

When we equate the function to zero, we obtai;

$x^2-576=0$

Use difference of two squares:

$x^2-24^2=0$

$(x-24)(x+24)=0$

Use the zero product property to obtain;

$x-24=0,\:and\:x+24=0$

This implies that;

$x=24,\:and\:x=-24$

The correct choice is C
