Answer: No, because 4(2) + 4 ≠ 9
Step-by-step explanation:
No, because 4(2) + 4 ≠ 9
1250x.08= 100+1250= 1350 / 120 is 11.25 so 11 months of paying $120 leaves a $30 12th month payment.
If triangles PQR and STU are similar then PQ corresponds to ST and PR corresponds to SU. Therefore, PQ/ST=PR/SU
Considering that, PQ= 7-x, ST= 13-x, PR= x²+5 and SU= x² +20
therefore, (7-x)/(13-x)= (x²+5)/(x²+20)
cross multiplying,
7x² +140-x³+20x =13x²+65-x³-5x
combining the like terms,
6x² +15x -75=0
solving for x,
x = 5/2 or -5
