17 and 3 are the two numbers
1. Distribute
7i × 5 + 7i × -9i
2. Simplify 7i × 5 to 35i
35i + 7i × -9i
3. Simplify 7i × -9i to -63ii
35i - 63ii
4. Use the Product Rule
35i - 63i^2
5. Use the Square Rule
35i - 63 × -1
6. Simplify 63 × -1 to -63
35i - (-63)
7. Simplify brackets
35i + 63
8. Regroup terms
63 + 35i
Step-by-step explanation:
By Sine Rule,
x/sin42° = 37/sin110°.
Hence x = 37sin42°/sin110° = 26.35 in. (A)
Answer:
14 - 4n
Step-by-step explanation:
g = 4n+1/n
n = 1/g−4
---------------------------------------
h = −2n+3/n
n = 3/h+2
---------------------------------------
g(- n + 3) = 4(- n + 3) + 2 = - 4n + 12 + 2 = 14 - 4n
I think its c.
