Answer:
= 39 - 10n
Step-by-step explanation:
There is a common difference between consecutive terms , that is
19 - 29 = 9 - 19 = - 10
This indicates the sequence is arithmetic with nth term ( expicit formula )
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 29 and d = - 10 , then
= 29 - 10(n - 1) = 29 - 10n + 10 = 39 - 10n
The image of the diagram is missing, so i have attached it.
Answer:
a = 30°
Step-by-step explanation:
From the diagram attached, we can see that the 2 angles a and 5a are interior supplementary angles.
The sum of interior supplementary angles is 180°
Thus;
5a + a = 180
6a = 180
a = 180/6
a = 30°
The answer is d because if u multiple it u will get 9000
Split the second term in 5x^2 + 23x + 26 into two terms
5x^2 + 13x + 10x + 26
Factor out common terms in the first two terms, then in the last two terms
x(5x + 13) + 2(5x + 13)
Factor out the common term; 5x + 13
<u>(5x + 13)(x + 2)</u>
