3
1.5 and 4.5 all are divisible by 1.5. Then you just have to find another number that is as well. I chose 3. Theres also 6, 7.5,9,10.5,12
Answer:
A
Step-by-step explanation:
(4+5)7=9*7=63
64/4 is 16
3 times 16 is 48
the answer is 48/64
When multiplying fractions, multiply straight across:
(-3/7) (6/5) =
(-3 * 6) / (7*5)=
-18/35
The answer is B.
(2x-1)(4x+1) just multiply the terms in the parentesis
Do the following:
2x*4x
2x*1
-1*4x
-1*1
You get:
8x^2+2x-4x-1
Final result:
8x^2-2x-1
