Answer:

Step-by-step explanation:

With this question, we just have to group the terms, so in this case, we can remove the common term (x - 4), and then group the rest of them

If we do that we get:

(x - 4) (2x + 7)

What is AE?<br> Enter your answer in the box?

Nataly [62]

Answer:

AE = 18 units

Step-by-step explanation:

Δ AEB and Δ DEC are similar , then corresponding sides are in proportion, that is

$\frac{AE}{DE}$ = $\frac{AB}{DC}$ , substitute values

$\frac{2x+4}{x+8}$ = $\frac{12}{10}$ ( cross- multiply )

10(2x + 4) = 12(x + 8) ← distribute parenthesis on both sides

20x + 40 = 12x + 96 ( subtract 12x from both sides )

8x + 40 = 96 ( subtract 40 from both sides )

8x = 56 ( divide both sides by 8 )

x = 7

Then

AE = 2x + 4 = 2(7) + 4 = 14 + 4 = 18 units
