I think u do 3•5 then divide by 110
Complete theh square
isolate x terms
factor out coefient of x^2 term
take 1/2 of 1st degree coefient and square it, add positive and negative inside parnthasees, expand
f(x)=(2x^2+12x)+7
f(x)=2(x^2+6x)+7
6/2=3, 3^2=9
f(x)=2(x^2+6x+9-9)+7
f(x)=2((x+3)^2-9)+7
f(x)=2(x+3)^2-19+7
f(x)=2(x+3)^2-12
Answer:
- 12 large rooms
- 8 small rooms
Step-by-step explanation:
If all were small rooms, 40 guests could be accommodated. Each large room accommodates 1 more guest, so there must be 52 -40 = 12 large rooms. The remaining 20 -12 = 8 rooms are small rooms.
Jayden reserved 12 large and 8 small rooms.
__
If you can't think without an equation, let x represent the number of large rooms. Then the number of guests accommodated is ...
3x + 2(20-x) = 52
x + 40 = 52
x = 52 -40 = 12 . . . . . . .number of large rooms
(20-x) = 20-12 = 8 . . . . number of small rooms
I can help, whats the question
