tesfa = x

dad = 4x

mom= 4x-1

x+4x+4x-1=101

9x+1=101

9x=100

100/9= 11.1

a regular polygon has a perimeter of 36 inches. each side is exactly 6 inches long. which figure does this discribe?
fgiga [73]
Since a side is only 6 inches long and the total perimeter is 36; take 36/6 and you get 6. The only figure with six sides is a hexagon, thus your answer is hexagon.

(14-3x)2 simplified using the distributive property.
ivolga24 [154]

Answer: 28-6x

This is the same as -6x+28

===============================

To get that answer, you multiply each term inside the parenthesis by the outer term 2

14 * 2 = 28

-3x * 2 = -6x

So,

(14-3x)*2 = 14*2 - 3x*2 = 28-6x

----------

The distribution rule says

a(b-c) = ab-ac

which is the same as saying

(b-c)a = ba-ca

We can flip things around because we can multiply in any order.
