Product is multiplication:
x * (x+2) = 201
x^2 +2x = 120
x^2 + 2x -120 = 0
(x+12) (x-10) = 0
x = -12 and x = 10
-12 x -1 = 12
the 2 numbers are 10 and 12
Answer: B and C only
Step-by-step explanation:
The temperature on a cold day starts at 0 degrees Celsius, falls 4 degrees, and rises 4 degrees
Initial temperature = 0
Temperature rise = 4
Fall in temperature = - 4
(Initial temperature + rise in temperature + fall in temperature)
Summing all : (0 + 4 - 4) = 0
carbon atom has 6 negatively charged electrons and 6 positively charged protons.
Net charge of atom :
(number of proton + number of electrons)
( 6 + (-6)) = 0
Answer: The required factored form of the given expression is
Step-by-step explanation: We are given to find the factored form of the following algebraic expression:
We will be using the following formula:
Now, we have
Thus, the required factored form of the given expression is
Answer:
(d) 428,820,000 pounds of garbage
Step-by-step explanation:
Your calculator or spreadsheet can give you the product of two numbers expressed in scientific notation.
(1.643×10^3 lb/resident) × (2.61×10^5 residents) = 4.28823×10^(3+5) lb
≈ 428.82×10^6 lb
= 428,820,000 lb . . . of garbage
