Answer:
486 cm
Step-by-step explanation:
9×9=81
there are 6 faces
81×6=486
y = ax^2
If the absolute value of a is <1 the graph is wider than when a = 1
If the absolute value of a is >1 the graph is narrow than when a = 1
The only function that fits that description is
y = 2x^2
The seamstress will need 12 inches of special fabric.
length = 15
let the width = w then length = 2w - 3
Perimeter = 2(length + width)
= 2(2w - 3 + w) = 2( 3w - 3) = 6w - 6 = 48
hence 6w = 48 + 6 = 54 ⇒ w =
= 9
Thus length = 2w - 3 = (2× 9) - 3 = 18 - 3 = 15
Look at the picture.
We have the similar triangles (AAA). Therefore the lengths of the sides are in proportion:

<em>multiply both sides by 8</em>
