Step-by-step explanation:
Answer:
A) 7 + 4(n - 1)
Step-by-step explanation:
The explicit rule follows the form, Tn = a + (n - 1)*(d), where 'a' is the first term and 'd' is the common difference between the numbers
It says that the first term is 7, so 'a' is 7. It also says that the numbers go up by 4 (adding 4 to the previous number), hence 'd' is 4.
Sub these values into the equation:
Tn = 7 + (n - 1)*(4)
Same as: 7 + 4(n - 1)
The answer is 4 (136y-21)
Explanation:
Factor 4 out of 544y.
4 (136y) - 12*7
Factor 4 out of -12*7.
4 (136y) + 4 (-3*7)
Factor 4 out of 4.
(136y) + 4 (-3*7)
4 (136y- 3*7)
Multiply -3 by 7.
4 (136y - 21)
Answer:
64
Step-by-step explanation:
4^3=64
4*4=16
16*4=64
Answer:
<h2>30.4</h2>
Step-by-step explanation:
sin x = 4.6/9.1
sin x = 0.5055
Thus , x = 30.4
