Answer:
A
Step-by-step explanation:
Noting that i² = - 1
Given
(7 - 3i)(8 + 4i) ← expand factors using FOIL
= 56 + 28i - 24i - 12i²
= 56 + 4i - 12(- 1)
= 56 + 4i + 12
= 68 + 4i → A
Answer:
An equilateral triangle is one with all three sides the same length. It begins with a given line segment which is the length of each side of the desired equilateral triangle. ... It is similar to the 60 degree angle construction, because the interior angles of an equilateral triangle are all 60 degrees.
Step-by-step explanation:
To round 2.83 centimeters to the nearest whole number, use the following:
"five or above, give it a shove. four or below, keep it low."
So, since the number is 2.83, keep the 3 low (make it a zero)
Now the number is 2.8
Since 8 is over 5, you round up.
2.83 has become the whole number 3
89+93+98 = 280
360 - 280 = 80 marks is needed for the last test
