Answer:

No Solution

Step-by-step explanation:

Assuming the lines are absolute value you must get rid of the other numbers first so:

5 |x+7| + 14 = 8

5 |x+7| = -6

and since absolute values can't equal a negative the answer is NO SOLUTION

Answer:

\Huge\boxed{\mathsf{\Rightarrow NO \quad SOLUTIONS}}

Step-by-step explanation:

<h3><u>TO FIND:</u></h3>

The solution of 5|x+7|+14=8.

Isolate x on one side of the equation.

<h3><u>SOLVE (SOLUTIONS):</u></h3>

First, subtract 14 from both sides.

\Rightarrow \displaystyle \mathsf{5\left|x+7\right|+14-14=8-14}

Solve.

\displaystyle \mathsf{14-8=6}

\displaystyle \mathsf{5\left|x+7\right|=-6}}

Then, divide by 5 from both sides.

\displaystyle \mathsf{\frac{5\left|x+7\right|}{5}=\frac{-6}{5}}

Solve.

Rewrite the equation problem.

\Rightarrow \displaystyle \mathsf{\left|x+7\right|=-\frac{6}{5}}

\Large\boxed{\mathsf{\Rightarrow THERE \quad ARE \quad NO \quad SOLUTIONS! }}

So, there are no solutions.

If nkf ~ lzf, find nf, please help me with this it’s due tmr!!!!
Ratling [72]

Answer:

NF = 25

Step-by-step explanation:

Since ∆NKF ~ ∆LZF, the ratio of their corresponding side lengths would also be the same.

This means that:

KF/ZF = NF/LF

KF = x + 3

ZF = 4

NF = 15 + x + 3 = x + 18

LF = x + 3

Plug in the values into the equation

(x + 3)/4 = (x + 18)/(x + 3)

Cross multiply

(x + 3)(x + 3) = (x + 18)(4)

x² + 3x + 3x + 9 = 4x + 72

x² + 6x + 9 = 4x + 72

x² + 6x + 9 - 4x - 72 = 0

x² + 2x - 63 = 0

Factorize to find x

x² + 9x - 7x - 63 = 0

x(x + 9) -7(x + 9) = 0

(x + 9)(x - 7) = 0

x + 9 = 0 or x - 7 = 0

x = -9 or x = 7

We'd use the positive value of x, which is 7.

Therefore, x = 7.

✅NF = 15 + (x + 3)

Plug in the value of x

NF = 15 + (7 + 3) = 15 + 10

NF = 25
