im assuming the 4 is an exponent, so (2 * 3 * 7)^4 = 2^4 + 3^4 + 7^4 because of the distributive property. the ^4 gets distributed to everything inside of the parentheses.
The answer is B) 30
parenthesis first (5×-3)(-2)
5×-3= -15
-15×-2= 30
'is' means =
so
X =
3X + Y = P
3X = P - Y
X = (P - Y) ÷ 3
