Answer:
A.) $0.89
Step-by-step explanation:
2(4x+3y=7.43)
-3(5x+2y=7.03)
8x+6y=14.86
-15x-6y=-21.09
add the two equations
-7x=-6.23
divide by -7
x=.89
Answer:
yes yes no no
Step-by-step explanation:
is that what u want
You can use this equation to help you: (ab)^2 = a^2 b^2. And also (a^m)^n = a^m*n
So, here it is:
(7ab^3)^2 = 7^2 a^2 b^3*2 = 49a^2b^6
The correct answer is the third one - 49 a^2 b^6.
