Set up an equation and solve:
2x-14=52
2x=66
x=33
sydney is 33 and devaughn is 19
Answer:
I’m pretty sure it’s 10
Step-by-step explanation:
Because the formula is something like baseXhight divided by two. and 2 times sixty is 120 so 120/12=10 that divided by 2 is five so the answer is either 5 or 10
Each piece is 7 and 1/3 feet long (7 feet 4 inches)
Answer:
1) For 
: 
and 
, 2) For 
: 
and 
Step-by-step explanation:
The polynomial 
is a second-order polynomial of the form 
. By direct comparison, we construct the following system of equations:
(1)
(2)
By (1) we know that there are a family of pairs such that the system of equations is satisfied. Let suppose that both 
and 
are integers. We assume two arbitrary integers for :
1)
2)
The number is -30
Exp
2/3=-20
1/3=-10
3/3=-30
