Answer:

Option B (n³ + 4n² + 8n - 16)

Step-by-step explanation:

In this question we have to add two expressions given

( 2n³ + 4n² - 7 ) and ( -n³ + 8n - 9 )

( 2n³ + 4n² - 7 ) + ( -n³ + 8n - 9 )

Now we group the similar terms

( 2n³ - n³ ) + 4n² - ( 7 + 9 ) 8n

= n³ + 4n² - 16 + 8n

= n³ + 4n² + 8n - 16

Option B (n³ + 4n² + 8n - 16) is the correct answer.

In kite ABCD, mZBAE = 28º and mZBCE = 58°. Find mZABE.<br> B<br> E<br> А<br> С<br> D<br> mLABE =
Digiron [165]

Answer:

m∠ABE = 62°

Step-by-step explanation:

Since, the given quadrilateral is a kite, diagonals will intersect at 90°.

Therefore, m∠AEB = m∠CEB = 90°

m∠BAE = 28° [Given]

m∠BCE = 58° [Given]

From ΔABE,

m∠BAE + m∠BEA + m∠ABE = 180°

28° + 90° + m∠ABE = 180°

m∠ABE = 180° - 118°

             = 62°

Therefore, measure of angle ABE = 62°.
