Answer:
I wasn't 100% sure what you were asking, but
Answer: x only can have complex values, not real values.
x = -1/4 - 1/4i and x = -1/4 + 1/4 i
Explanation:
Finding the possible values of x in the expression given is solving the quadratic equation.
8x² + 4x = - 1
Rearrange the terms:
8 (x² + x/2) = - 1 ← common factor 8 in the left side
x² + x/2 = - 1/8 ← division property
x² + x/2 + 1/16 = - 1/8 + 1/16 ← addition property
(x + 1/4)² = -1/8 + 1/16 ← -factor the perfect square trinomial in the left side
(x + 1/4)² = - 1/16 ← add the fractions in the right side
x + 1/4 = (+/-) √ (-1/16) ← square roots on both sides
x + 1/4 = (+/-) (1/4)i ← complex solution
x = - 1/4 +/- 1/4i
x = - 1/4 - 1/4i and x = - 1/4 + 1/4 i ← answer
No it is not. that is a right scalene triangle. Acute triangle has three angles less than 90.
Metric: kilometers
Imperial: Miles
Answer:
None of the above
Step-by-step explanation:
To find the GCF of something find the prime factorization of each number, then see which numbers are the same. After that multiply the numbers that are the same.
(PF): Prime Factorization
A: PF - 1 PF - 2 · 3 (Since they don't have any numbers in common the GCF is 1)
B: PF - 2 PF - 3 (The GCF is also 1)
C: PF - 2 PF - 2 · 3 (Because they have 2 in common the GCF is 2)
D: PF - 3 PF - 2 & 2 (The GCF is 1)
None of the options have a GCF of 3. Therefore it is none of the above
