1. N + 2; n = 6: the answer is 8 because n=6 so we sub n with that... and we get 6+2 and that’s 8.
2.5f; where f=4: the answer is 20 because when a variable is directly next to a number it is multiplied by that number so we will replace f with 4 and our equation is now 5(4) or 5•4 and both are equivalent to 20.
3. 7b-2; where b=5: the answer is 33 because 7 multiplied by 5(b) minus 2= 7(5)-2 or 7•5-2= 33 because you will multiply 7 by 5 and get 33 then you will subtract by 2 and get 33.
Hope this helps!!!
Answer:
Step-by-step explanation:
The answer is factor the trinomial
700 x .03 x 20 = 420
420 + 700
1120 is in the account after 20 years
He should take breaks every 15 minutes and he should also eat a healthy snack and drink lots of water
Subtract the cost from the revenue:
(-0.32x^2+270x) - (70x+52)
270x - 70x = 200x
The answer would be -0.32x^2 + 200x + - 52
