Answer:
the answer are x=4y-20
and x represents the independent variable and y represents the dependent variable
Step-by-step explanation:
the electromagnet lasts only as long as there is supply of electric current
1.754
Because without the decimal 54 is more than 48 (a little trick I used)
Let the width be x
Length= x+7
Area=lw
99=(x+7)(x)
99=x²+7x
0=x²+7x-99
x= -14.04 or x=7.04
Since a length cannot be negative, the width is 7.04 ft and the length (7.04+7)=14.07 ft
Hope I helped :)
