Answer:
20
Step-by-step explanation:
You use the distributive property.
Distribute the 2 to whatever is inside the parentheses. (You will multiply)
4×2=8
2×6=12
Substitute the answers above into the parentheses.
(8+12)=20
Answer:
p' (4,-2)
Step-by-step explanation:
P is at ( -1,5)
We are moving it 5 units to the right so add 5 to the x
We are moving it 7 units down so subtract 7 from the y
p'( -1+5, 5-7)
p' (4,-2)
Degree is exponent, so 5th degree
difference of 2 perfect squares
a^2-b^2=(a-b)(a+b)
t^2-5^2=(t-5)(t+5)
2nd one
complete square
take 1/2 of linear coefient and square it
-6/2=-3, (-3)^2=9
add that to both sides
x^2-6x+9=-8+9
x^2-6x+9=1
factor
(x-3)^2=1
sqrt
take neg and pos root
x-3=+/-1
add 3
x=3+/-1
x=3+1 or x=3-1
x=4 or 2
3rd option
Answer:
3.00x10^8
Step-by-step explanation:
So you want to make sure the number before the x10^ is beween 10 and 0 not including 10 and 0. So 1.00-9.99.
Move the demcil place up in 300,000,000 till your first number is between 1 and 9.99.
Then count how many places you moved it up, in this case 8
Add the amount of times you moved up to the x10^(in this space).
you answer is now 3.00 plus the x10^8
3.00x10^8
Answer:
P = (nRT)/V
Step-by-step explanation:
Step 1: Write formula
PV = nRT
Step 2: Divide both sides by V
P = (nRT)/V
