You would have to take 42 and multiply it by .20 and get tht number and add it back to 42
Answer:
28
Step-by-step explanation:
Use the pythagorean theorem and solve for a:
a² + b² = c²
a² + 21² = 35²
a² + 441 = 1225
a² = 784
a = 28
So, the missing length is 28.
Answer:the answers 128
Step-by-step explanation:
Since there are like terms, you can combine them
5a-2a = 3a
So, then you get
3a+9
Then you can factor to get a GCF of 3
3(a+3)
Answer:
Yes
Step-by-step explanation:
The answer is proportional because the variables correspond directly to each other.
1=225
2=450
3=675
4=900
