a[n] = 7n - 16
The fifth term is a[5]
a[5] = 7(5) - 16 = 35 - 16 = 19
Answer: C. 19
Answer:
a(5) = 2 + 5^2 = 2 + 25 = 27
Step-by-step explanation:
This sequence is defined as a(n) = 2 + n^2.
Thus, a(1) = 2 + 1^2 = 2 + 1 = 3
Then a(5) = 2 + 5^2 = 2 + 25 = 27
Hello there!
First off, I appreciate you asking for the steps so you can fully understand how to conclude this because you can't use Brainly on a test - it won't be useful whatsoever then..
But i'm here and ready to help !
So a rectangle has four sides, two sides are bigger than the other two.
Draw a rectangle.. write 13 on the two longer sides of the rectangle then write 7 on the other two shorter ones. Then add them all up and there you go your answer!
Our equation would be 13 + 13 + 7 + 7 = 40 inches
Do not forget your label!!
Hope this helped you!
Answer:
2a + 20b +2xc = 2(a+10b+xc)
Step-by-step explanation:
Let a = one litter box, b = one cat toy and c = a bag of cat food
The 1 litter box = a, 10 cat toys = 10b and x bags of cat food = xc
For one sister, purchase = a + 10b + xc
And for two sisters,
total purchase = 2 x ( a + 10b + xc ) = 2(a+10b+xc)
= 2a + 20b + 2xc
