Answer:
4 feet and 2 inches
Step-by-step explanation:
1 foot = 12 inches
x feet = 50 inches
1/12 = x/50 --> 50/12 --> 4 feet and 2 inches
Begin by following the herd . . . call the two numbers 'x' and 'y' .
You said that xy=1 , so y = 1/x
You said that x + y = 10, so x + 1/x = 10
Multiply each side by 'x': x² + 1 = 10x
Subtract 10x from each side: x² - 10x + 1 = 0
Use the quadratic formula to solve this, and the two solutions
that you get for 'x' are also the two numbers 'x' and 'y' .
They are
<em>9.89898</em>
and
<em>0.10102</em>
(rounded)

Answer:
Perimeter = 6t - 4
Area = 2t² - 7t - 3
Step-by-step explanation:
Given length = 2t + 1
Width = t - 3
So perimeter = 2t +1 + t - 3 + 2t + 1 + t - 3
= 2t + t + 2t + t + 1 - 3 + 1 - 3
= 6t - 4
Area = (2t + 1)(t - 7)
= 2t² - 6t + t - 3
= 2t² - 7t - 3
Sorry if im wrong but i think thats the answer
