Answer:
rational
Step-by-step explanation:
irrational is something like pi or square root of 3, -27 is a simple number.
Let x be the number.
"twelve decreased by twice a number" ---> 12 - 2x
"8 times the sum of number and 4" ---> 8(x + 4)
12 - 2x = 8(x + 4)
12 - 2x = 8x + 32 (distributive property)
12 = 10x + 32 (add 2x to both sides)
-20 = 10x (subtract 32 from both sides)
x = -2 (divide both sides by 10)
Answer: V= 4500m^3
Explanation:
V= length x width x height
V = 600 x 3 x 2.5
V = 600 x 7.5
V = 4500
Answer: It would be 4b+44
Step-by-step explanation:
This is the distributive property! so a(b+c)=ab+ac
In this case–4b+44!
