X+4
Product is the answer to a multiplication.
The multiplicative inverse is the same as the reciprocal.
(5x+20) x 1/5= 5x+20/5
=x+4
let length = x
width is 7 feet less than length
width = x-7
area = length *width
area = x(x-7)
170=x²-7x
x²-7x-170=0
x²-17x+10x-170=0
x(x-17)+10(x-17)=0
(x-17)(x+10)=0
x=17 or x=-10
since length cannot be negative so x=17
and width =x-7 =17-7=10
length =17 feet and width =10 feet

Answer:
43.4 mph
Step-by-step explanation:
super simple, you can disregard all the speed stuff, since they are both hours, it is useless information. all you have to do is convert distances, so multiply 70 by .62 to get 43.4milers per hour.
