1 answer:

8 0

$2x-8 - (2x+7)^2\\\\=2x-8 -(4x^2 + 2\cdot 2x \cdot 7 + 7^2)\\\\=2x-8-(4x^2 + 28x +49)\\\\=2x - 8 -4x^2-28x -49\\\\=-4x^2 -26x -57\\\\$

Answer:

Step-by-step explanation:

Δ AQP and Δ ACB are similar triangles, thus the ratios of corresponding sides are equal, that is

$\frac{AQ}{AC}$ = $\frac{PQ}{BC}$ ( note that AC = 3 + 6 = 9 ), substitute values

$\frac{3}{9}$ = $\frac{4.5}{BC}$ ( cross- multiply )

3BC = 40.5 ( divide both sides by 3 )

BC = 13,5 cm → C

4x + 7x - 10x - 10 + 14 + 2

x + 6 is the simplified version of the equation.
