(x+2)-3(x-4)=6 and x=4

DENIUS [597]

Explanation:

If you plug 4 in for x into the equation, the equation becomes this:

$(4+2)-3(4-4)=6$

When you simplify the equation;

$(6)-3(0)=6$

Simplify it further,

$6-0=6$

That is correct. 6 = 6

What’s.the perimeter of a square with an area of 49 cm2

Free_Kalibri [48]

Answer:

Step-by-step explanation:

Area of a square =

$s^2$

Perimeter =

$4\times s$

Where s = side

Solve for s using the area

$A =49\\\\49 = s^2\\\\Square\:root \:both\:sides\:of\:the\:equation\\\\\sqrt{49} = \sqrt{s^2} \\\\7 =s\\\\s =7$

Find the perimeter

$4\times s\\\\= 4 \times 7\\\\= 28$

Solve for n 19 + 10n = 7n - 20

kakasveta [241]

Answer:

n = -13

Step-by-step explanation:

19 + 10n = 7n - 20

Subtract 7n from each side

19 + 10n-7n = 7n-7n - 20

19+3n = -20

Subtract 19 from each side

19+3n -19 = -20-19

3n = -39

Divide each side by 3

3n/3 = -39/3

n = -13
