22, 29, 37
Step-by-step explanation:
There is a pattern to find the next number in the sequence. The sequence is taking the previous number and adding the number it is in the sequence.
Notice how the first number being added is the number of the previous sum and the second number being added is always increasing by one
1+0=1
1+1=2
2+2=4
4+3=7
7+4=11
11+5=16
16+6=22
22+7=29
29+8=37
22, 29, 37
Answer:
fourth option
Step-by-step explanation:
note that (
)(x)x) = 
= 
← factorise numerator/ denominator
= 
← cancel the common factor (2x + 1)
= 
where x ≠ 0, - 
<span>f(x) = 5x − 10 and g(x) = x + 3
</span>f(g(x)) = 5(x + 3) − 10
f(g(x)) = 5x + 15 − 10
f(g(x)) = 5x + 5
when x = -1
f(g(-1)) = 5(-1) + 5
f(g(-1)) = - 5 + 5
f(g(-1)) = 0
