One number is 7 less than another. Their product is 60. What are the two numbers?

Answer 1

Let x be the smaller number
Let x+7 be the larger number

Then x (x + 7) = 60

Expand out:
x² + 7x = 60

Subtract 60 from both sides:
x² + 7x - 60 = 0

Factor:
(x - 5)(x + 12) = 0

So the answers are:
x = 5 or x = -12.

I'm assuming you want positive numbers (5 and 12), but negative numbers also work (-12 and -5).

Answer 2

12 & 5

Answer 3

5 & 12

Answer 4

the two numbers are 12 and 5
12x5=60
12-5=7

Answer 5

Lies, poverty and the ever reducing life variety of standard individuals is what maximum get from the trickle-down concept. maximum of my artwork is interior the main important, self-contained retirement community interior the U.S., it extremely is called The Villages and found in powerful Florida. i does no longer call those people great wealthy yet i'm valuable a lot of them might nicely be called millionaires. those are the folk who fought interior the 2nd worldwide conflict and decrease back to usa to pass to artwork for usual electric powered, Ford, GM, Westinghouse, RCA, and so on. The Nineteen Fifties, the place one in 3 workers in usa belonged to a union. life grew to become into stable, companies have been stable and persons made a competent living. someplace alongside the line of this suited subject the place all people grew to become into creating wealth, somebody or a team of somebodies desperate they weren't making adequate and the slow destruction of the middle-type grew to become into began and it has quickened by way of the years to what we've. it extremely is the techniques of those in power, a lot of that are from company usa who later grow to be politicians who then pass law to further channel the wealth of usa to a go with team in enormous corporation, with the lie of trickle down linked. there is not any such concern as unfastened industry, it extremely is all manipulated, condensed by way of mergers strangling opposition and giving corporation an iron fist to contol their own destiny on the rate of the generally going on worker. Throw in thousands and thousands of illegals taking the decrease paying jobs in usa and the staff who earn the least go through the main. To me trickle down skill the greater those on the precise can save, the less trickles down. For those sufficiently old who can look lower back on the Nineteen Fifties, are you able to merely say trickle down economics has made this united states greater effective at present than it grew to become into then?

Answer 8

See it's easy now practice more so that you get it and can solve it ont he test. All you have to do is to break the q down. Look and see what each one of these people did here.

Answer 9

x(x-7)=60
x^2-7x-60=0
(x-12)(x+5)=0
x=12 or -5
the nos are 15,5 and -5,-12
