Answer: -7
Step-by-step explanation:
Down = -
Up = +
Therefore we know to subtract 14 and add 7,
next we do 0 - 14 = -14,
after that we do -14 + 7 = -7,
so we get -7 as the answer.
First you get figure out that Tara must have 1/3 of the shells from the other two ratios. Then you learn that 76 is 1/3 of the shells, therefore there must be 76*3 or 228 shells total.
-30a^5b+12a^4b^3+16a^3b^2-4a^2b^4-2ab^3
x=4, because 10+(4*2)=10+8=18 and since it is a rectangle the sides are the same.
