Area of a parallelogram= base*height
A=14*8
A=112m²
The area of this figure is 112m²
We all are familiar with (x,y) coordinate plane where some lines or curves are drawn. These curves are drawn or made up using some (x,y) points. These values of (x,y) points satisfy the equation of curves.
The equation of x and y variables is called a Relationship. Now, a Function is a "special relationship of x and y variables" where each input x has a single answer for output y.
In other words, we can say any relation y=f(x) would be a "Function" if and only if each value of x input give us a unique value of y output from the equation. No two values of y can be output of same x-value input.
For example:- y = f(x) = 2x is a Function because each value of x would give unique answer for y. x=4 gives y=8.
Another example is:- y = f(x) = √x is "not a function" because one-value of x would give two answers of y. x=4 gives y= -2 and y=2.

we see we doulbe the 3 to add
3*2=6
6+12=18
6+15=21
thelength and width of the surfface is 18 by 21
P=2(L+W)
P=2(21+18)
P=2(39)
P=78
the perimiter is 78ft
Answer: 4.5 metres
Step-by-step explanation:
Using Hooke's Law ()
We need to find the spring constant of the bungee cord with the given extension and force, we can do this by substituting in known values.
Now we have found the spring constant of the bungee cord, we can substitute it in for the a different force. As the cord is the same we can use the same spring constant.
Joseph is going to pay full price for the higher priced book so we start with 15 dollars. Then he pays 50% of the second book which is 10 dollars, so we find 50% of 10 and then add it to 15...
15 + 50% x 10 =
15 + .5 x 10 =
15 + 5 = 20
He pays a total of $20
