Answer:
Step-by-step explanation:
roots are (2+3i) and (2-3i)
reqd. eq. is (x-2-3i)(x-2+3i)=0
or (x-2)²-(3i)²=0
or x²-4x+9-9i²=0
or x²-4x+9+9=0
or x²-4x+18=0
Answer:
19d + 11
Step-by-step explanation:
7(d + 2) - 3 (1- 4d)
Expand the brackets.
7d + 14 - 3 + 12d
Add or subtract like terms.
7d + 12d + 14 - 3
19d + 11
<span> Final price=(Initial price)(100%-discount rate)
Final price=($415.80)(100%-20%)
Final price=($415.80)(80%)
Final price=($415.80)(0.8)
Answer:
Final price=$332.64 </span>
The statement, m∠4 = m∠5, then then r||s is true based on the converse of corresponding angles theorem.
<h3>What is the Converse of Corresponding Angles Theorem?</h3>
Based on the converse of corresponding angles theorem, if two corresponding angles, angles 4 and 5 are congruent or equal to each other, then the lines on which they lie on, lines r and s are congruent.
Therefore, based on the converse of corresponding angles theorem, m∠4 = m∠5, then then r||s.
