Answer:

Option A.

Step-by-step explanation:

1. BC ║ ED [Given}

2. m∠ABC = 70° [Given}

3. m∠CED = 30° [Given]

4. m∠ABC = m∠BED [Corresponding angle theorem]

5. m∠BEC + m∠CED = m∠BED [Angle addition postulate]

6. m∠BEC + 30° = 70° [Substitution property of equality]

7. ∠BEC = 40° [Subtraction property of equality]

Therefore, option A is the answer.

If -1 is zero of polynomial p(x) =ax square -3(a-1)x-1 then find the value of a.

frez [133]

Answer:

a = 1

Step-by-step explanation:

Since x = - 1 is a zero of p(x) then p(- 1) = 0

Substitute x = - 1 into p(x)

p(- 1) = a(- 1)² - 3(a - 1)(- 1) - 1 = 0, that is

a + 3(a - 1) - 1 = 0

a + 3a - 3 - 1 = 0

4a - 4 = 0 ( add 4 to both sides )

4a = 4 ( divide both sides by 4 )

a = 1
