You start off by multiplying the second bracket by -1 to get rid of the bracket.
So,
(2x3 + x2 - 4x) - 9x3 + 3x2 =
2x3 +x2 - 4x - 9x3 + 3x2 =
(2x3 - 9x3) + (x2 + 3x2) - 4x =
-7x3 + 4x2 - 4x
Answer:
The Area = 28.26 or 28.27 depends if you round or not
Answer:
The correct answer is second option 60°
Step-by-step explanation:
From the figure we can write,
measure of arc AEC = measure of arc AE + measure of CE
measure of arc ACE = measure of AC + measure of CE
measure of arc AEC + measure of arc ACE = 280 + 140 = 420°
measure of arc AE + measure of CE + measure of AC + measure of CE = 420
measure of arc AE + measure of CE + measure of AC = 360°
measure of CE = 420 - 360 = 60°
The correct answer is second option 60°
The median is 1 because that is the number in the middle
