Answer:
The shape has 6 angles and 6 sides
Step-by-step explanation:
therefore it is a hexigon as hexigon is a polygon of six angles and six sides.
<span>b-3/15=-1
We simplify the equation to the form, which is simple to understand
<span>b-3/15=-1
Simplifying:
<span>b-0.2=-1
We move all terms containing b to the left and all other terms to the right.
<span>+1b=-1 + 0.2
We simplify left and right side of the equation.
<span>+1b=-0.8
We divide both sides of the equation by 1 to get b.
<span>b=-0.8

Answer:
6500 cm^3.
Step-by-step explanation:
That would be the volume of the large box - the volume of the cube
= 15*25*20 - 10^3
= 7500 - 1000
= 6500 cm^3.

Answer:
11) x = 9
12) x = 9
Step-by-step explanation:
11) Corresponding segments are proportional, so ...
x/6 = 12/8
x = 6(12)/8 . . . multiply by 6
x = 9
__
12) Similar triangle relationships show you the geometric mean relationship that applies in this case.
long side/short side = x/3 = 27/x
x² = 3·27 . . . . . . cross multiply
x = √(3·27) . . . . geometric mean relationship
x = 9
