He will get 1111.111111 when he changes the money
Answer:
y = -9
Step-by-step explanation:
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>
The answer is 76.99 but rounded would make it 77.00 which is C
If 6X6 = 36
And b=3
5(3)= 15
So 36+15= 51
