23rd term : is -70
Number one is but number two is not
of more than 1 dot is on an “up and down” line then it’s not a function
Let the width = x
=>length = 2x-1
91= x(2x-1)=2x^2-x
2x^2-x-91=0
=(2x+13)(x-7)
=> x=-13/2=> no
=>x= 7 cm
I think this is the answer ----> 8.7 (8.66 rounded)
Y-y1=m(x-x1)
y-5=10(x-1)
Y-5=10x-10
Y=10x-5
