2/a= a/50
Cross multiply:
a* a= 2*50
⇒ a^2= 100
⇒ a= √100 or a= -√100
⇒ a= 10 or a= -10
Final answer: a= 10 or a= -10~
Answer:
A. 12
Step-by-step explanation:
Selecting B, C, or D would create a difference of perfect squares since each of these numbers are perfect squares. Additional factoring would then be needed.
But selecting 12 gives 
which cannot be factored. It is factored completely.
Because for input=-2 there are more than one outputs. It means the this is not a function and it’s impossible to find a rule.
Answer:
2.86$
Step-by-step explanation:
first you must find out how much she is spending since she is buying 2.8 pounds of asparagus that are 2.55 per pound you can just times 2.8 x 2.55 its the same as if it were a dollar for a pound it would be 1 x 1 except in the case of this question it is a decimal number. Now that you know how much she spent you would subtract it from 10 since that's the amount she gave the cashier so you subtract the cost from how much she gave and you will get how much change she will get.
