Answer:
lhs = (5+2√3)/(7+4√3)
= [(5+2√3)(7-4√3)]/[(7-4√3)(7+4√3)]
=[35-20√3+14√3-24]/[7²-(4√3)²]
=[11-6√3]/[49-48]
=11-6√3
therefore
11-6√3 = a+b√3
compare both sides
a= 11, b= -6

Answer:
You put a equal sign or if its one equation then put a addition or subtraction sign etc.
Step-by-step explanation:
Well 75x12=900 so 900 divided by 40 is 22.5 so 22 teachers can have 40 chalks but the principal needs to order another 20 :)
5200 - 700 = 4500
25 words per minute
25 × 60 = 1500 words (1 hour)
4500 ÷ 1500 = 3
Answer: 3 hours
