14. x ^2 = 12^2 + 7 ^2 = x = sqrt (12^2 + 7^2) = sqrt(193)
Answer:
x=3
Step-by-step explanation:
Use pemdas!
First use distributive property to get rid of the parenthesis, by multiplying 2 by 3x and -4. Then combine like terms and use inverse operations to simplify each side until you get it down to just x! Hope this helped! :)
The answer is 30,60,90. Because 60 is twice the number 30 and 90 is three times the first number.
The first one is 212
and the second one is 158
so yes it is false they do not equal
In a trapazoid the diagonals are the same so therefore the two equations equal echother
3x+7=5x-11 solve for x by combining like terms
18=2x then divide to unto multiplication
9=x
9 is the value of x
I hope I've helped!
