Step-by-step explanation:
1. 2, 4, 6, 8, ...
This sequence has a common difference (+ 2). So it is arithmetic.
2. 9, 16, 25, 36, ...
This sequence has neither a common difference nor a common ratio.
3. 64, 32, 16, 8, ...
This sequence has a common ratio (× ½). So it is geometric.
If it is a geometric sequence, then ur answer would be d.
Answer:
x is 7.5 so the answer is D
Step-by-step explanation:
Since the triangles are similar, you can flip the 1st one to match the 2nd.
Now you can write
16/12=10/x
(the 9 is irrelevant)
now cross multiply to solve for x
12x10=120
120/16=7.5
x is 7.5
Answer:
The x-intercepts of the graph of the function are -9 and 4
Step-by-step explanation:
- factor the function f(x)=x²+5x-36
- f(x)=(x+9)(x-4)
- x = -9, 4
