(didnt forget this time)

2nd choice down

$929.84

Step-by-step explanation:

3.19*36=114.85

114.84+815=929.84

7) 1.75c+7.50. If you knew the amount of cupcakes you would multiply that number by 1.75, but you don't know it, so we represent it with c. If you only pay the 7.50 one time, then there's nothing to multiply it to.

8) $929.84. Multiply 36 gallons × $3.19 per gallon, and you get $114.84. Then, add the $815 for the Airbnb and you get $929.84

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
