The problem states that ABC and DEF are similar. Therefore, dsue to similar triangles, we have 7x/7=4/x, so x^2=4. Therefore, x=2 (because x cannot be negative). Therefore, AB = 7x = 7*2=14

hello

the question here is

$3\sqrt[]{7}(14-4\sqrt[]{56})$

step 1

multiply through the bracket by the coeffiecient

$\begin{gathered} 3\sqrt[]{7}(14-4\sqrt[]{56}) \\ (3\sqrt[]{7}\times14)-(3\sqrt[]{7}\times4\sqrt[]{56}) \\ (14\times3\sqrt[]{7})-3\sqrt[]{7}\times4\sqrt[]{4\times14} \\ (42\sqrt[]{7})-3\sqrt[]{7}\times8\sqrt[]{14} \\ (42\sqrt[]{7})-\lbrack(3\times8)\sqrt[]{7\times14} \\ 42\sqrt[]{7}-24\sqrt[]{98} \end{gathered}$ $\begin{gathered} 42\sqrt[]{7}-24\sqrt[]{49\times2} \\ 42\sqrt[]{7}-24\times7\sqrt[]{2} \\ 42\sqrt[]{7}-168\sqrt[]{2} \end{gathered}$

Select the graph for the solution of the open sentence. Click until the correct graph appears. 2|x| + 1 < 5

Paul [167]

Answer:

The correct answer is x < 2 or x > -2. The graph would be a line between -2 and 2 with an open circle on both.

Step-by-step explanation:

To solve, first solve the equation for the absolute value portion of the equation.

2|x| + 1 < 5

2|x| < 4

|x| < 2

Now since there is an absolute value around it, we have to complete it for the positive and negative versions.

x < 2 OR x > -2
