Given x = -25, y = 3

x + y + 5 = ?

Prove that the value of the expression 7^8–7^7+7^6 is divisible by 43.

Merrida uses a pattern in the multiplication table below to find ratios that are equivalent to 7: 9. if merrida multiplies the first term, 7, by a factor of 6, what should she do to find the other term for the equivalent ratio? multiply 9 by 1. multiply 9 by 6. multiply 9 by 7. multiply 9 by 9.
