Answer: No she is not.
Step-by-step explanation: The correct answer is 7.25 F, because she just put them both as positives. When you have a negative it takes away from the total, so how I think of it is you subtract from the positive number, so you could just do 11.75-4.5. Hope this helped!
x+y = -19
x*y = 35
x=-19-y
(-19-y)y = 35
y^2 +19y +35 = 0
y = -2.066965626
therefore x=35/y = -16.93303437
Answer:
$20
Step-by-step explanation:
49 is the outlier
A=138° B=180° C=180° D=138°
This is because angle QRS and QTS would equal 180° Bc they are supplementary. So 180-42=138. And since they are supplementary and vertical angles, angle ST would also be 42° and QT would also be 138° because angle RS is 138°
