Answer:
Length = 30.4 ft
Width = 3.6 ft
Step-by-step explanation:
Width: x
Length: 4x + 16
2(x) + 2 (4x + 16) = 68
2x + 8x + 32= 68
10x = 68 - 32
x = 36/10
x = 3.6
Width = 3.6 ft
Length: 30.4 ft
Answer:
a. -216, 0 real roots
Step-by-step explanation:
The discriminant of ...
ax² + bx + c = 0
is ...
d = b² -4ac
When we put your equation into the standard form shown above, we get ...
7n² +8n +10 = 0
Then we can identify a=7, b=8, c=10. The discriminant is then ...
d = 8² - 4·7·10 = 64 -280 = -216
___
The interpretation of the discriminant is ...
- < 0; no real roots (2 complex roots)
- = 0; one real root (multiplicity 2)
- > 0; 2 real roots
Your discriminant is -216, so there are 0 real roots.
