Answer:
the value of x-1/x is given down
Step-by-step explanation:
=(x+1/x)²=x²+1/x²+2
=(5)²=x²+1/x²+2
=x²+1/x²=25-2
=x²+1/x²=23 this is the answer
if u ask there how 25 came means there (5)² is that u should multiply 5×5 and u will get 25bas the answer
His gross pay would be $525.00
2500-1000=1500
1500 x .15 = 225.00
225+300= $525.00
Answer:
288
Step-by-step explanation:
Find the 18 on the x axis. Go up to the line. Then go left and you will be at 288 on the y axis.
You can also divide a known coordinate to find the rate of change, since the graph is proportional. Use (6, 96). y/x = rate of change
96/6 = 16.
Now multiply 18 and 16 to get the number of cookies.
18 x 16 = 288
This is a question that will require Pythagoras' theorem as you want to find the length of a diagonal of a triangle and are given the measurements of two sides. I have attached a picture of how to solve this problem.
To the nearest 10th of a foot, the answer is 77.6ft
Perimeter is just the addition of the side lengths so add them together:
5c+6 + 2c+5 = 7c+11
Option D.
