So for the first question, you basically add up all of the sides. So it would be 3y+5+3y+1+2y+6+2y+3y-4+2y+2y+8+4y-2
To simplify that combine like terms so 17y+14
For the second part of the question, it's easy algebra.
Here's your problem 17y+14=77
To solve that get the variable by itself, subtract the constant, 14, from both sides.
17y+14 -14=77 -14
17y=63
Now divide each side by the coefficient, 17
y=3.71
I might be wrong in my math somewhere, but the method is the same... you might want to check it to make sure.
The scientific notation of this number would be 81500000e-1

Answer:
B
Step-by-step explanation:
Let's go through each set of dimensions and test them. Keep in mind that two times the sum of the length and width of a rectangle yields the perimeter.
A) 2(12+10)=2(22)=44
B) 2(50+10)=2(60)=120
This works! Therefore, the correct answer is choice B. Hope this helps!
