Answer:
-16 - 30i
Step-by-step explanation:
(3-5i)^2 = (3-5i) * (3-5i)
Applying the "FOIL" method of expanding this expression through multiplication, we get:
9 - 15i - 15i - 25 (since i^2 = -1)
Simplifying this result, we get -16 - 30i
Answer:
First: 1/4
Second: 3/5
Step-by-step explanation:
FIRST:
You can easily solve this problem by creating a slope triangle between the points given.
1 up
———————- = 1/4
4 to the right
SECOND:
To solve for slope with two points, you do y1-y2/x1-x2.
1-4 -3
—— = — = 3/5
-3-2 -5
Its a prime number the factor of it are 1,2,4,19,38,76,152.
Answer:
8x + 20 ≥ 25
Step-by-step explanation:
Well 8 times the sum of a number "x" plus 20,
So we can write the following,
8x + 20
and that should be greater than or equal to 25
8x + 20 ≥ 25
<em>Thus,</em>
<em>as an inequality it is 8x + 20 ≥ 25.</em>
