Answer:
213$
Step-by-step explanation:
24$ on headphones
189$ left
so you add the use and what is left an u get 213$ do not forget to write $ when u are finished :)
we have
(a+b)(3a-b)(2a+7b)
step 1
Solve
apply distributive property
(a+b)(3a-b)=3a^2-ab-3ab-b^2=3a^2-4ab-b^2
step 2
Multiply (3a^2-4ab-b^2) by (2a+7b)
6a^3+21a^2b-8a^2b-28ab^2-2ab^2-7b^3=6a^3+13a^2b-30ab^2-7b^3
answer is
<h2>6a^3+13a^2b-30ab^2-7b^3</h2>
Proportional because there is no + x at the end<span />
Volume=hpir^2
d/2=r, 24/2=12=r
h=40
v=40pi12²
v=40pi144
v=5760pi cubic inches per section
