12•5=60. That’s the answer
Answer:
![5\frac{1}{4}](https://tex.z-dn.net/?f=5%5Cfrac%7B1%7D%7B4%7D)
Step-by-step explanation:
Greatest multiplier of 4 that is less than 21 is 5 (4 x 5 = 20)
Put the remaining number as the numerator (21 - 20 = 1)
Answer:
add 21 to both sides to get everything on one side
x^2 - 10x + 21 = 0
do factorization, guess and check
(x - 7) (x -3) = 0
x =7, and x =3
