Let h represent the number of hours Liam must ride to beat his record.
distance-ridden + distance-to-ride ≥ record-distance
distance-ridden + (speed × time-to-ride) ≥ record-distance
4 +7h ≥ 32 . . . . . . . . an inequality representing the distance Liam wants
7h ≥ 28 . . . . . . . . . . subtract 4
h ≥ 4 . . . . . . . . . . . . . divide by 7
He must ride for more than 4 hours.
It's B. the sides of a square have to be equal, so you can check by squaring any of the options and seeing which ones equal 225. 15 is the square root of 225. this can be expressed as 15=sqrt225
It is A. when you synthetic divide you end up underneath 2 7 0. the 0 is the remainder. the other makes 2x+7
A+S=589
S=a-61
A+A-61=589
2a=589+61
2a=650
A=325
S=325-61
S=264
