Answer:
118
Step-by-step explanation:
15x - 2
Substitute the value given, in this case, it's x = 8.
15(8) - 2
Multiply 15 and 8.
120 - 2
Subtract 2 from 120.
<em>1 656 m³</em>
<em>V = B×h/3</em>
<em>= 92m²×54m/3</em>
<em>= 92m²×18m</em>
5760
40%
24/60 is 40%
Don't know if there was supposed to be another option but, it would be distribute over (x - 8).
