Answer:
a7 = 38
Step-by-step explanation:
n is the term indicator
an = 5n+3
Let n=7 if we are looking for the 7th term
a7 = 5*7 +3
a7 = 35+3
a7 = 38
Answer:
295 SUVs were sold, and 215 passenger vehicles.
Step-by-step explanation:
Let s and p represent the number of SUVs and p the number of passenger cars.
Then s = p + 80 and s + p = 510.
Substitute p + 80 for s in the second equation, obtaining:
p + 80 + p = 510, or:
2p = 430
Dividing both sides by 2 isolates p: p = 215.
Since s = p + 80, we add 80 to 215 here, obtaining s = 295.
295 SUVs were sold, and 215 passenger vehicles.
Answer:
x² + 5x + 6
Step-by-step explanation:
Foil means first, outside, inside, last
First: (x+2)(x+3)
x × x = x²
Inside: (x+2)(x+3)
x × 3 = 3x
Ouside: (x+2)(x+3)
2 × x = 2x
Last: (x+2)(x+3)
2 × 3 = 6
adding them together:
x² + 3x + 2x + 6 = x² + 5x + 6
