1. The square on the inside is 8 x 8 = 64
2. The triangle's area is 8x9x1/2= 72 x 1/2 = 36
3. there are 4 triangles so 36 x 4 = (or 72 x 2 ) = 144 :)
Answer:
If we are solving x + 5< 6 the inequality is x< 1
Step-by-step explanation:
If helps mark as brainllest please!!!
You would do an arithmetic sequence
use A1 +(n-1)d to calculate number of seats in the last row
An = 4+(24-1)5
An = 4 + (23)(5)
An = 4 + 115
An = 119 seats in the last row
now use a sum sequence to find total number of seats
Sn = n(a1 + an)/2
Sn = 24(4+119)/2
Sn = 24(123) /2
Sn = 1476 total seats
Answer:
The answer is T=-5
