Answer:
The answer to your question is
a) 400
b) The function has two real solutions (-2 and 8)
Step-by-step explanation:
Process
1.- Discriminant = b² - 4ac
= 12² -4(-2)(32)
= 144 + 256
= 400
2.- Solutions (using the general formula)
x = 
x = 
x = 
x₁ = 
x₂ = 
This function has two real solutions (-2, 8)
Answer:
(-1, 3)
Step-by-step explanation:
Answer:
d= 90 degrees
e= 99 degrees
f= 81 degrees
Step-by-step explanation:
To find d, you know that the other side is equal to 90. Because two sides that are opposite of each other must be equal to 180, you do 180-90 which is 90 to get d. Therefore, d=90 degrees. 99 degrees and e are alternate interior angles so that means they have to be the same. Because f is on the other side of 99 degrees and two sides that are opposite of each other must equal 180 degrees, you have to do 180-99 which is equal to 81 degrees. Therefore, d=90 degrees, e=99 degrees, and f=81 degrees
