(x+12)^2=(x+12)(x+12) = x^2 +12x + 12x + 144
= x^2+24x+144
Answer:
y = 10x +
the picture is cut short so I can't help with the next box.
Answer:
No.
Step-by-step explanation:
For there to be a equal sign, it will mean that both sides will have to have the same exact amount. If it is expressions on both sides, then the expressions must, when combined, equal to each other.
In this case, there is not given operation that will allow for both numbers to equal each other, and 17.8 is 10 less than 18.8, therefore it is not reasonable.
17.8 ≠ 18.8
Answer:
and Liz can ship maximum 19.6 pounds.
Step-by-step explanation:
Let the possible weight of the medium flat-rate box = w pounds.
It is given that there is a box weighing 6 ounces i.e. 0.375 pounds.
Plus, the maximum weight of the package is 20 pounds.
So, we get,
The inequality representing the situation is,
Weight of medium box + 0.375 pounds ≤ Maximum weight of the package
i.e. 
i.e. 
i.e. 
Thus, Liz can ship maximum 19.6 pounds.
