We could answer this if we were able to see the other questions. ;-;
42 is the numerator you multiply 8 times 6 so you do the same with the top

Here we go ~

[ add 2 on both sides ]

[ form identity : a² + b² + 2ab ]

[ a² + b² + 2ab = (a + b)² ]



so, the value of required expression is 6
[usually positive value is considered, but if asked the value can be either positive or negative]
Answer:
165x>_ 175y
Step-by-step explanation:
Car #1 is x while Car #2 is Y, since Car #1 went at least the same amount of distance of car #2, it means that Car #1 either went farther or has the same distance as car #2. (Make sure you choose greater than or equal to sign not greater than!)
