Answer:
width = x - 5
Step-by-step explanation:
x² - 25 = x + 5 × width
(x + 5)(x - 5) = x + 5 × width
x - 5 = width
width = x - 5
The area of the blanket - 24 ft²
length being longer than the width means that blanket is a rectangle
width of the blanket = x
length of blanket = x +2
area = length * width
area = x * (x+2)
= x² + 2x
since area = 24
x² + 2x = 24
x² + 2x - 24 = 0
we have a quadratic equation and we need to now solve for x
x² + 6x - 4x - 24 = 0
x (x + 6) - 4(x + 6) = 0
(x-4) (x+6) = 0
x-4 = 0 or x + 6 = 0
x = 4 or x = -6
x could be either 4 or -6. since dimensions cannot have negative values,
x ≠ -6
therefore x = 4
width = 4 ft
length = 6 ft
The volume of <span>a right square pyramid is
, where </span><span>
is basis area.
</span>
If the lengths of the sides of the base remain fixed and height
<span>is multiplied by a factor 10, than new height is
and the volume is
</span>
