(22,11) it equals the about when you plug it in
Answer:
Step-by-step explanation:
㏒ 3+㏒(x+2)=1
㏒3(x+2)=1
3(x+2)=10^1
3x+6=10
3x=10-6=4
x=4/3
so A

To find the number of seats, let's do it using multiplication!
First, to see how many seats are in one big section of the theatre, multiply 7 groups of seats by 25 seats:
7 x 25 = 175
Now, knowing this, multiply 175 by 4 to get the total number of seats in the theater!
175 x 4 = 700
Therefore, there are 700 seats in the theatre.
Hope this helps!
Answer:
438.97 cm²
Step-by-step explanation:
To find the surface area, we break up the figure into two pieces(blue and yellow) and then add them together.
SA = 2(w · l + h · l + h · w)
2 · (6 · 16 + 4 · 16 + 4 · 6)
368 cm²
70.97 cm² + 368 cm²
438.97 cm²
