-sqa(3.24-sqa(1.44+sqa(12.25)))

= -sqa(3.24-sqa(4.94)) (since sqa(1.44+sqa(12.25))=sqa(4.94))

=-sqa(3.24-2.22261)

= - sqa(1.01739)

= - 1.00866

Z is the midpoint of YA. If YZ = x + 12, and ZA = 6x - 13, what is YA?
fgiga [73]

Answer: YA=7x-1

Step-by-step explanation:

You know that "Z" is the midpoint of "YA". This means the following:

YZ+ZA=YA

Now, you know that the expression for "YZ" is:

YZ = x + 12

And the given expression for "ZA" is:

ZA = 6x - 13

Knowing these expressions, you can substitute them into YZ+ZA=YA, as following:

( x + 12)+(6x - 13)=YA

Finally, you must add these expressions in order to get "YA".

Therefore, this is:

x + 12+6x - 13=YA\\\\7x-1=YA\\\\YA=7x-1
