That question is rly badly organized but i think it’s 70
Answer:
17.5
Step-by-step explanation:
a^2+b^2=c^2
15^2+9^2=306^2
square root of 306= 17.49
4(2x5 + 3) - 4(2) + 2(5).
4(13) - 18.
52-18 = 34.
Answer:
-40x
Step-by-step explanation:
f(x) =-3x-5
g(x) =4x-2
(f+g)(x) =?
now,
f(g(x))
=f(4x-2)
=-3×4x-2-5
=-10×4x
=-40x
Answer:

Step-by-step explanation:
The recursive rule tells you the initial term of the sequence is a1 = -3, and the common difference is d=7. (7 is the value added to one term to get the next term.)
Putting these values into the formula for the explicit rule gives ...
an = a1 +d(n -1)
an = -3 + 7(n -1)
