The expression is h=6x2 which means that h is 12 feet
We shall proceed in graphical method
Graph all 4 functions
Reason:-
It depends upon coefficient
In graph 4 the coefficient outside root is negative so it is decreasing
<u>Answer-</u>
<em>The length of line segment WU is</em><em> 4 cm</em><em>.</em>
Option 1. 4 cm is correct.
<u>Solution-</u>
As given that, RSTU is an parallelogram.
RT and SU are its two diagonals. They intersect each other at point W.
Properties of parallelogram is that they bisect each other.
i.e SW = WU and RW = WT
As given that, SW = 4 cm.
So, WU = SW = 4 cm
Therefore, the length of line segment WU is 4 cm.
Let the two numbers be x and y, then
x + y = 62 . . . . . . . (1)
x - y = 18 . . . . . . . .(2)
subtracting (2) from (1), we have:
2y = 44
y = 22
From (2), x + 22 = 62
x = 62 - 22 = 40
therefore, the two numbers are 40 and 22.
