Since they have the same base we can just add all the exponents
-3+ 10= 7
keep the base so the answer is
12^7
35% Just move the decimal place forward two places. That's how i LEARNED IT

Answer: a) -27, b) 35, c) 14
Step-by-step explanation:
a) When a positive number is multiplied by a negative number, your answer is negative, and since we know that 9 × 3 = 27, and that this figure has to be negative (since 9 is negative), the answer is -27.
b) Multiplying two negative numbers gives a positive number, and since 7 × 5 = 35, the answer is positive 35 (as both 7 and 5 in the original question are negative).
c) Follows just like b.
Answer:
-3
Step-by-step explanation:
X = 40, Y = 15
40(2) + 15(2) = 80 + 30 = 110 :)
