-5, work backwards. you know 2 + 4 * ? = -18.
start by subtracting 2 from both sides giving you 4 * ? = -20.
now you divide 4 from both sides giving you ? = -5
i used ? to represent the missing number btw!!

32.6-8.25=24.35
Answer:
B
Step-by-step explanation:
This is a power to a power problem. -3 times 2 equals-6. Usually when a number is raised to a negative power, the number is the denominator over 1...with the exponent in the denominator ad well. 5 to the -6 power is 15,605 which is the same as 1/5 to the 6th power....1/15,605
y(x+3)2 then (-2x-6)2
is you have to distribute 2 like
2x+6=-4x-12
-2x -2x
6=-2x-12
+12 +12
-2x=0
x=0
Answer: a = 12
Step-by-step explanation:
Volume = lwh
PRISM A
4 * 3 * x = 72
12x = 72
x = 6
PRISM A * 2 = PRISM B
4 * 3 * a = 72 * 2
12a = 144
a = 12
