Answer:

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides , thus

180 (n - 2) = 1260 ( divide both sides by 180 )

n - 2 = 7 ( add 2 to both sides )

n = 9

Ax- bx > 2a-2b solve for x

Dima020 [189]

Answer:

If a<b, x<2

If a>b, x>2

Step-by-step explanation:

ax-bx>2a-2b, (a-b)x>2(a-b)

If a>b, x>2(a-b)/(a-b)=2

If a<b, x<2(a-b)/(a-b)=2

Scilla [17]

Answer:

$7x^2+28x$

Step-by-step explanation:

$7x(x+4)\\\\Multiplication\ is\ distributive\ on\ addition\\\\\Rightarrow 7x(x+4)=7(x\times x+x\times 4)\\\\7x(x+4)=7(x^2+4x)\\\\Multiplication\ is\ distributive\ on\ addition\\\\\Rightarrow 7x(x+4)==7\times x^2+7\times 4x\\\\7x(x+4)=7x^2+28x$
