Answer:
20i² + 38i
Step-by-step explanation:
4i(7+6i)+2i(5-2i)
28i + 24i² + 10i - 4i²
24i² - 4i² + 28i + 10i
20i² + 38i
Either of two angles whose sum is 90 degrees
d=28g I might be wrong, but we can find this by dividing 140 by five, which equals 28.
Subtract 15 from both sides that gets rid of 15 and your left with 3b =30b divide 3 on both sides and the answer is 10
Answer:
1/10 + 1/2 = 1/10 + <em><u>5/10</u></em> = <em><u>6/10</u></em>
