Answer:

4x -9

Step-by-step explanation:

First, expand it by multiplying (x+4) with -2.

(x + 3) - 2(4 + x) + 5x - 4

= x + 3 - 8 - 2x + 5x - 4

Then, collect like terms. Add up the coefficient of x, and the whole numbers separately.

= x - 2x +5x + 3 -8 -4

= 4x -9

When nothing can further be simplified, you get the answer.

Which expression is equivalent to 4 over 9 (2n - 3)

AlexFokin [52]

Answer:

The result for this equation is $\frac{8}{9}n - \frac{4}{3}$ .

Step-by-step explanation:

-Solve:

$\frac{4}{9} (2n-3)$

-Multiply $2n$ and $-3$ by $\frac{4}{9}$ :

$\frac{8}{9} + \frac{-12}{9}$

-Reduce $\frac{-12}{9}$ to the lowest term by extracting and canceling out 3:

$\frac{8}{9}n - \frac{4}{3}$

-So, the result is $\frac{8}{9}n - \frac{4}{3}$ .

The diagram shows a right-angled triangle.

Otrada [13]

Answer:

h ≈ 9.9 cm

Step-by-step explanation:

By applying tangent rule for the given angle in the given right triangle,

tan(51°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

tan(51°) = $\frac{h}{8}$

h = 8 × tan(51°)

h = 9.879

h ≈ 9.9 cm

Therefore, measure of side 'h' is 9.9 cm.
