This is as simplified as it gets since there are none of the same variables.
Answer:
utv = 2x-57 = 41
stv = x = 49
Step-by-step explanation:
x+2x-57=90
3x=147
x=49
Answer:
x = 3 ± sqrt(11)
Step-by-step explanation:
x^2 - 6x + 9 = 11
Recognizing that this is a perfect square trinomial
(x-3) ^2 =11
Taking the square root of each side
sqrt((x-3) ^2) = ± sqrt(11)
x-3 =± sqrt(11)
Add 3 to each side
x = 3 ± sqrt(11)
QT=16
this is false because i got it right on the test
