Translate 5 units to the right, and 2 units down
1) an = a1 + d*(n-1) => a20 = -4 + (-9)*19 = -4 - 171 = - 175
1) ---> C)
2) a81 = 20 + 4*80 = 340;
2) ---> A)
3) a12 = ?
3) ---> B) or D).
Lol is it hard I don’t get it are you okay 2+2=4 -1=3 quick maths
Answer:
(f - g)(x) =
+ 8x + 4
Step-by-step explanation:
(f - g)(x)
= f(x) - g(x)
=
+ 10x - (2x - 4) ← distribute parenthesis by - 1
=
+ 10x - 2x + 4 ← collect like terms
=
+ 8x + 4
There are many solutions. But what do you mean with a perfect square of a number. I thought a number IS a perfect square or not.
For example, the difference between 2² and 4² = 12, which is twice the number 6, which is √36
The difference between 2² and 6² = 32, which is twice the number 16, which is a perfect square.
So choose depending on your interpretation of the question... ;-)
