What expression should replace A,B,C
ser-zykov [4K]

Answer:

A = 5x + 3y

B = 8x + 5y

C = 15x + 11y

Step-by-step explanation:

B = 6x + 2y + 2x + 3y

= 6x + 2x + 2y + 3y

= 8x + 5y

C = 8x + 5y + 7x + 6y

= 8x + 7x + 5y + 6y

= 15x + 11y

A = 7x + 6y - 2x - 3y

= 7x - 2x + 6y - 3y

= 5x + 3y

Which expression is equal to 5^4 x 5^8 ? <br><br> A: 5^12<br> B: 5^4<br> C: 5^2<br> D: 5^−4
galben [10]

Something to remember is how to multiply terms with same bases, but different exponents:

a^b \cdot a^c = a^{(b+c)}


Essentially, we add the exponents.


Using the information above, we can find our answer:

5^4 \cdot 5^8 = 5^{(4+8)} = \boxed{5^{12}}


Our answer is \boxed{5^{12}}, or A.
