Length=width+x
l=w+x (x being the amount of feet longer than the width)
Fam,
Take the average boundary of it. So it would be 8 * 4 = 32.
Thus, it must be less than 32 and most likely greater than 20 so its B!
Basically, we are to find the area of the television screen. Because a TV is rectangular in form, the formula for the area is written below:
A = L×W
The given dimensions are 64 inches in length and 52 inches in width. But that includes the edges. To compute for the screen area only, we subtract 4 inches (2 inches on both sides) to each dimension.
A = (64 - 2)(52 - 2)
A = 3,100 square inches
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
We have to triple Autumn's earning for each basket, so the table would be
We expect an equation like
where is the initial value, and is the multiplier. Since we start with 2$, and we triple the amount with each basket, we have
This relation is exponential, because every time a new basket is made, the previous amount is multiplied by a constant. In other words, we have
For the graph, you just need to sketch the points from the table we draw above and connect them
