The solution for proving the identity is as follows:
sin(2A) = sin(A + A)
As sin(a + b) = sinacosb + sinbcosa,
<span>sin(A + A) = sinAcosA + sinAcosA
</span>
<span>Therefore, sin(2A) = 2sinAcosA

Answer:
j = -3, -4
Step-by-step explanation:
j^2 + 7j + 12 = 0
(j + 3)(j + 4) = 0
j = -3, -4
Answer:
30 ways
Step-by-step explanation:
Given the following information:
- 3 different sandwiches
- 2 different salads
- 5 different drinks
Let assume that the combo contains: 1 sandwich, 1 salad, and 1 drink
Hence, we have:
- The total possible ways of choosing sandwiches she can choose is: 3
- The total possible ways of choosing salads she can choose is: 2
- The total possible ways of choosing drinks she can choose is: 5
=> Total ways = 3*5*2 = 30 ways or there are 30 different combos Keisha can choose
Hope it will find you well.
