Answer:
<h3>
Jake is 13 years old</h3>
Step-by-step explanation:
D - age of Dani
J = D+2 - age of Jake
E = 2J = 2(D+2) = 2D+4 - age od Ethan
Z = 2E = 2(2D+4) = 4D+8 - age of Zoe
The sum of their ages is 102:
D + J + E + Z = 102
D + D+2 + 2D+4 + 4D+8 = 102
8D + 14 = 102
-14 -14
8D = 88
÷8 ÷8
D = 11
J = 11+2 = 13
The answer is B. 4 yards.
You're trying to find the length of the field in yards, which is L, so to do that you would have to isolate L. Subtract 9 from both sides, which would give you 7L=37, then divide 7 by both sides, L=4.
The perfect square can be expanded as follows:
So, we have to think of the term as , which implies .
Thus, we have to add , i.e. 16, to complete the perfect square:
