4 0

Answer:

x=-\frac{17}{28}

Step-by-step explanation:

\frac{1}{4}(4x-1)=-\frac{1}{7}-\frac{5}{7}

x-\frac{1}{4}=-\frac{6}{7}

x = -\frac{6}{7} + \frac{1}{4}

x = -\frac{17}{28}

plug x in the equation to make sure of your answer:

\frac{1}{4}(4x-1)=-\frac{1}{7}-\frac{5}{7}\\\frac{1}{4}(4(-\frac{17}{28}) -1)=-\frac{1}{7}-\frac{5}{7}\\-\frac{17}{28} -\frac{1}{4}=-\frac{6}{7}\\-\frac{6}{7}=-\frac{6}{7}

2x^2+4x+2
Carry the 2 over to the 3 behind the 4 and multiply so 2times2 is 4. So i new equation is.
X^2+4x+4
Now you have to find the factors of 4 which is 1,4 and 2,2
So now you have to see which one adds up to 4 so 1+4 is 5 so cross that out and 2+2=4.
So the two number is 2 and 2 now you have to bring down the x^2 and the signs.
(X+2) (X+2) and thats your answer

Simplify the expression:<br><br> 5x + 8 – 13y – 4x – 18 + 16y
aleksandrvk [35]

\text{Hey there!}

\text{Simply the equation: 5x + 8 - 13y - 4x - 18 + 16y}

\text{First you have to combine the \bf{like-terms}}

\text{5x-4x = 1x}

\text{-13y + 16y = 3y}

\text{8 + (-18) = -10}

\boxed{\boxed{\bf{Answer: 1x + 3y - 10}}}\checkmark

Please brake down why !
lana66690 [7]

Answer:

D

Step-by-step explanation:

using the rule of radicals

• \sqrt{a} × \sqrt{b} ⇔ \sqrt{ab}

simplifying \sqrt{32}

\sqrt{32} = \sqrt{16(2)} = \sqrt{16} × \sqrt{2} = 4\sqrt{2}

\sqrt{32} + 5\sqrt{2}

= 4\sqrt{2} + 5\sqrt{2} = 9\sqrt{2} → D
