Answer:
-12r² + 10xr - 15x + 34r - 24
Step-by-step explanation:
1. Organize it, variables first - as well as adding constants such as 4 and -7
(5x - 6r + 8) (2r - 3)
2. Start by multiplying the 5x by (2r - 3), then -6r, followed by 8
(10xr - 15x) + (-12r^2 + 18r) + (16r - 24)
3. Simplify
10xr - 15x - 12r² + 18r + 16r - 24
4. Order by greatest to smallest factorial
-12r² + 10xr - 15x + 18r + 16r - 24
5. Combine like variables
-12r² + 10xr - 15x + 34r - 24
Answer:
q≤7
Step-by-step explanation:
q+8≤15
1) Subtract 8 from both sides:
q≤7
My answer is a and c becuase they equal the same on each side

Answer:
B.)536 
Step-by-step explanation:
Find the volume of all the fish tanks.
Green fish tank...
4 x 9 x 6 = 216
Brownish fish tank...
4 x 4 x 8 = 128
Orange Fish tank...
6 x 4 x 8 = 192
Since we are COMBINING the fish tanks, we add the volumes.
216 + 128 + 192 = 536
536
