150+150+2x=960 (width+width+2 length=perimeter)
subtract 300 from each side
2x=660
divide by 2
x=330
the length is 330 ft
In this type of calculations, we decompose 13 by checking the lowest powers of the base, that is 40. for example we check 40^2, or 40^3 and compare it to 85
Notice
40*40*40=64,000
so we check how many time does 85 fit into 64,000:
64,000/85=752.94
85*753=64,005; 64000-64,005=-5
this means that

thus

Answer: 10 (mod85)
Remark, the set of all solutions is:
{......-75, 10, 95, .....}, that is 85k +10
I really sorry I have to do this I'm in a test I need help
Answer:

4 1
Step-by-step explanation:
To convert division problems with fraction into multiplication problems use the KCF rule
- Keep the 1st Fraction the same
- Change the division sign to a multiplication sign
- Flip the fraction (reciprocal)
