Answer:
No you can't.
Step-by-step explanation:
4 is an integer, and 2x isn't so you can't add them together. If 4 was 4x or 2x was 2, then you'd get 6, but you can't add them. Hope this helps :)
X^2 - 8x + 13 = 0
subtract 13 from both sides
x^2 - 8x = -13
-8/2 = -4, (-4)^2 = 16, add 16 to both sides
x^2 - 8x + 16 = -13 + 16
factor the left side
(x - 4)^2 = 3
Answer:
$3100
Step-by-step explanation:
You can determine this by multiplying 52 by 50, because you get 50 dollars for 52 weeks, then add 500 to it, because you get 500 dollars at first. 52 times 50 is equal to 2600, and 2600 + 500 is equal to 3100. You will receive $3100 over the course of 52 weeks.
Answer:
49.4
Step-by-step explanation:
So, 1 Gallon = 3.8 Liters. We need to find how many liters are in 13 gallons.
All we need to do is multiply our 3.8 liters (1 gallon) by 13 to find out how many liters 13 gallons is.
3.8 x 13 = 49.4
Your answer is 49.4.
