Simplifying the expression (x - 2y) + (3x + 4y).
Work:
(x - 2y) + (3x + 4y)
Combine like terms.
x + 3x = 4x
-2y + 4y = 2y
Reform the expression.
4x + 2y
Simplified Expression: 4x + 2y.
Answer:

Answer:√(6/5) and √(9/7) and √(7/5)
Step-by-step explanation:
1/4 = 0.25
5/4 = 1.25
√(6/5)=1.095445...
√(9/7)=1.1338934...
√(7/5)=1.1832159...
Thus, any non-perfect square radicals will be irrational numbers.
Hope this helps!! :)
Please let me know if you have any question
A rectangle with maximum area is always a square
a square has the same length and width.
to find the length of the side of a square with the known area, you would take the square root of the area
so in this case, the side length = square root of 100
square root (100) = 10 ( check: 10 x 10 = 100)
so both the length and the width equal 10 meters
Answer:
37
Step-by-step explanation:
3x + 8x + 4x = 6x + 63 ( combine like terms)
>15x = 6x + 63 (subtract from both sides)
-6x. -6x
-----------------
>9x = 63. (divide both sides by 9)
--------------
9. 9
> x = 7 ( use this to plug in for your new equation)!
5(x) + 2
>5(7) + 2 (multiply 5*7)
> 35 +2 (then add)
> 37 is your answer
