-7(n - 2) + 2n = -5(n + 6)

skad [1K]

Given the expression below

$-7(n-2)+2n=-5(n+6)$

To find n

Open the brackets

$\begin{gathered} -7(n-2)+2n=-5(n+6) \\ -7n+14+2n=-5n-30 \\ -7n+2n+14=-5n-30 \\ -5n+14=-5n-30 \end{gathered}$

Collect like terms

$\begin{gathered} -5n+14=-5n-30 \\ -5n-(-5n)=-30-14 \\ 0\ne-44 \end{gathered}$

Since, the sides are not equal,

Hence, there is no solution

Use the side-splitter theorem to solve for x in the triangle below.

fiasKO [112]

Answer:

$x = 7$

Step-by-step explanation:

According to the side-splitter theorem, the two sides of the triangle is divided proportionally if the line that intersects both sides is parallel to the third side of the ∆.

Therefore, based on this theorem, we would have the following:

$\frac{x}{21} = \frac{8}{24}$

Solve for x

$\frac{x}{21} = \frac{1}{3}$

Multiply both sides by 21

$\frac{x}{21}*21 = \frac{1}{3}*21$

$x = \frac{21}{3}$

$x = 7$
