Try this solution/explanation:
<u>way 1</u>:
rule: for an equation where no roots P+Q=0. It means, Px-Qx=0, ⇔ x(P-Q)=0, ⇔ P=Q.
for answer 'D' P=Q=15.
<u>way 2</u>:
rule: if an equation of the line has a form y=kx+b, then y₁||y₂ if k₁=k₂. It means, for y₁=Px-45 || y₂=Qx+75, then P=Q. P=Q, if 'D' answer.
Answer: D
Answer:
7
Step-by-step explanation:
42/ 6 = 7
42/48 is equivalent to 7/8
Answer: False.
Step-by-step explanation:
48 is not a common factor of 4 and 6
4 and 6 only share 2 factor: 1 and 2
Factors in 4: 1, 2, 4
Factors in 6: 1, 2, 3, 6
Every time they are divided by 2
