Answer: A or B im unsure but its one of them
Step-by-step explanation: dont got one sry
Part a b2+49−(b−7)2
Distribute:
=b2+49+−b2+14b+−49
Combine Like Terms:
=b2+49+−b2+14b+−49
=(b2+−b2)+(14b)+(49+−49)
=14b
Answer:
=14b
part b
(2a+6b)2−24ab
Distribute:
=4a2+24ab+36b2+−24ab
Combine Like Terms:
=4a2+24ab+36b2+−24ab
=(4a2)+(24ab+−24ab)+(36b2)
=4a2+36b2
Answer:
=4a2+36b2
46. 6*3=18 hence x=9*3=27 (ratio is 3:1)
47. x=8 clearly 2:1 ratio.
48.ratio is 1/3 hence, x=9/3=3
49.7:1 ratio. so, x=70
I hope you got the hang of it. so do the last two yourself.
