Answer:
Step-by-step explanation:
1. complex conjugate two complex numbers of the form a + bi and a - bi, whose product is always a real number
2. imaginary root a complex number of the form a + bi, where b ≠ 0, that satisfies the polynomial equation
3. repeated root a solution to a polynomial equation that appears more than once
You did an excellent job matching the definitions to the vocabulary word
Answer:
Either a= -7 or a= 0
Step-by-step explanation:
Pull out like factors:
a2 + 7a = a • (a + 7)
a • (a + 7) = 0
Combine like terms first (so like the ones that have x with x and someone please help them bc I explained it bad
Rates are used to measure a quantity over another.
<em>The 1.8 million cars use </em>
<em> liters each year</em>
Given

--- distance

First, we calculate the number (n) of gallons used by each car

Solve for n

So, we have:


Convert miles to kilometers



The number of gallons (N), used by all the cars is:


Convert to liters


In scientific notation to 2 decimal places, we have:

<em>Hence, the number of liters used is </em>
