Answer:
1
Step-by-step explanation:
Co-efficient means the integer in front of the variable
The co-efficient for -4x^3 would be -4 like that
Answer: k = {8, -8}
<u>Step-by-step explanation:</u>
In order for a quadratic equation to have exactly one solution, the discriminant must equal zero. → b² - 4ac = 0
4x² + kx + 4 = 0
↓ ↓ ↓
a=4 b=k c=4
b² - 4ac = 0
k² - 4(4)(4) = 0
k² = 64
k = √64
k = ± 8
Answer: 6600 cu in
Step-by-step explanation: (12*10*40=4800)+(10*10*18=1800)=6600
Answer:
3/8
Step-by-step explanation:
(3/8) Since they have the same denominator, you can subtract the second numerator from the first so 6 minus 3 is 3. So 3/8
