I'm not entirely sure, but I believe its $7.95
This is how I got it:
8.00/100=0.08
(1.30+1.80+0.08)2 1/2 (or 2.5)
=(3.18)2 1/2
=7.95 ==========> $7.95
Again, I'm not 100% sure if this is correct...
Answer:
3(3r - 4)(3r + 4)
Step-by-step explanation:
I can't see the writing very clearly.
This is the correct solution:
27r^2 - 48 Divide through by 3:
= 3(9r^2 - 16) 9r^2- 16 is the difference of 2 squares so:
= 3(3r - 4)(3r + 4)
Answer:

Answer:
The chalkboard costs $54.00
Step-by-step explanation:
A chalkboard is in a shape of a rectangle. The chalkboard mentioned measures 1 meter by 2 meters.
The area of a rectangle is given by the formula:
