Answer:
C. Both expressions involves addition.
Step-by-step explanation:
Answer: -25; -5
Step-by-step explanation:
Let's write a system of equations. Lets call x and y the numbers, where x is 5 times y.
x + y = -30
x = 5y
Plugging this in, we get:
5y + y = -30
y = -5
Since y = -5, we can plug this in, and see that x = -25.
Answer:
I think you need to multiply 12 and 7 and then cut that in half
A^4 * a^6
exponent rule : x^y * x^z = x^(y + z)
so, a^4 * a^6 = a^(4 + 6) = a^10
