Answer:
2 ± i
Step-by-step explanation:
by 5, I assume you mean +5
x² - 4x + 5 = 0
x = (-b±(√(b²-4ac)) / 2a
x = (4 ± (√(16 - 20)) / 2
x = (4 ± (√(-4)) / 2
√-4 = √4√-1 which is 2i
x = (4 ± 2i) / 2
x = 2 ± i
Answer:
y > 24 − 3x
Step-by-step explanation:
Step 1: First, you need to factor out the common term 2.
2 (3x + y) > 48
Step 2: Then, you divide both sides by 2.
Step 3: Next, you have to simplify into 24.
3x + y > 24
Step 4: Lastly, subtract 3x from both sides and you're done!
y > 24 − 3x

Answer:
Step-by-step explanation:
When you find the volume of prisms, you're essentially taking the area of the base and multiply it by the length, in varied orientations.
In this case, I'd start by finding the area of the parallelogram facing us.
The formula for a parallelogram's area is the same as a rectangle's:
A = b x h
In this case, h = 3 cm and b = 8 cm.
A = 24 cm²
Now, you multiple the area by the length of the parallelogram, which is 8 cm.
V = 24 cm² x 8 cm
= 192 cm³
I hope this helps!
