Answer:
-4
Step-by-step explanation:
You multiply -13*-4=52
Hello,
The correct answer is 5 Liters.
2 Liters of water = 2000 Milliliters.
If she drinks 400 Milliliters per hour, then you do 2000 ÷ 400 to work out the number of hours.
2000 ÷ 400 = 5
Hope this helps!!!! :)
96 messages .... $4.80
155 messages .... x
x= (155x4.80):96=7.75
Steps
1. Do long division so 16 on out and 3744 on inside
2. Find how many 16s go in 37 only 1 so 16 under 37 add two 0s and and on the outside on the side it's 100.
3. Then u subtract 3700 from 1600 and get 2144
4. Then only one 16 goes in 21 so it's another hundred and then subtract 2144 from 1600 and get 544.
5. Then find how many 16 go into 54 only 3 then add a 0 on the 3 and after subtraction get 480 after that subtract 544 from 480 and get 64
6. four 16 go into 64 and then u get 234 as a answer
Answer:
It is a perfect square expression.
It factors to (x+2)^2
===========================================================
Explanation:
The general format for a perfect square is
(a+b)^2 = a^2 + 2ab + b^2
Which can be seen through the use of the FOIL rule.
Compare x^2+4x+4 with a^2+2ab+b^2, and we have these three equivalences:
- x^2 = a^2 .... first terms
- 4x = 2ab .... middle terms
- 4 = b^2 .... last terms
Since x^2 = a^2, we can apply the square root to both sides to get a = x. Similarly, 4 = b^2 leads to b = 2. We could get b = -2, but that would mean 2ab = 2x*(-2) = -4x instead of 4x. So we'll stick with b = 2 instead.
Because a = x and b = 2, we then can say:
(a+b)^2 = a^2 + 2ab + b^2
(x+2)^2 = x^2 + 2*x*2 + 2^2
(x+2)^2 = x^2 + 4x + 4
Showing that x^2+4x+4 factors to (x+2)^2.
