Answer:
Step-by-step explanation:
Recursive sequences generally look like this:
a1 = something
an= ahhhhhh
The 1st term in this sequence is 11.
So we have
a1=11
And now we see that each term is adding by 22.
We have,
a1=11

Answer:
-9y+19
Step-by-step explanation:
Answer:
9x^2+42x+45
Step-by-step explanation:
Foil (3x+5)(3x+9) by taking the numbers in the left parenthesis and multiplying it by the numbers on the right. So 3x(3x), then 3x(9), then 5(3x) and 5(9). Now we have 9x^2 + 27x+15x+45, simplify to get 9x^2+42x+45.
The height of the shed, h, is 12.5.
lwh = 1500
(12) x (10) x h = 1500
120 x h = 1500
(120 x h)/120 = 1500/120
h = 12.5
Hope this helps!
For the 2nd equation u have to divide 3 for both sides so y can be alone so it will be y=3x+6
