Answer:
6/2(1+2)
the 2 will divide 6 or go into 6 ,how many times, 3 times because 2*3=6
next 1+2=3
therefore 3(3) =9
(2x² + 6x + 10) + (4x² + 2x + 3)
Remove the parentheses and bring like terms together ( as there's a positive outside the parentheses the terms inside keep their signs):-
= 2x^2 + 4x^2 + 6x + 2x + 10 + 3
= 6x^2 + 8x + 13 answer
Answer:
1/5
Step-by-step explanation:
You have to do whats in the parentheses first then you start doing to exponets from left to right then you would multiply then you would get your answer 1/5.
Answer:
The answer to your question is: 3200 bottles
Step-by-step explanation:
1 tank = 500 gallons
how many ounce bottles can be filled from the tank?
1 gallon = 128 ounces
1 gallon --------------------- 128 ounces
500 gallon ---------------- x
x = 500(128) / 1
x = 64000 ounces
20 ounce bottles = 64000 / 20
= 3200
Answer:
When they are equal, y=y, so we can say:
x^2+5x-2=x+1 subtract x from both side
x^2+4x-2=1 add 2 to both sides
x^2+4x=3, now add half the linear coefficient squared, (4/2)^2=4
x^2+4x+4=3+4 now the left side is a perfect square
(x+2)^2=7 now take the square root of both sides
x+2=±√7 subtract 2 from both sides
x=-2±√7
x=-2+√7 and -2-√7
y=x+1 the two points where these equations are equal are:
(-2-√7, -1-√7) and (-2+√7, -1+√7)
or approximately:
(-4.65, -3.65) and (0.65, 1.65)
