Answer:

We will write each part of this sentence:

The product of 4 and x: This means 4 and x are getting multiplied, so 4x

Less than or equal: This is what we mean with this symbol $\leq$

About how many miles are in 16,300 ft

Studentka2010 [4]

Urgent help ! similar figures use the similarity relationship to find the indicated value

masya89 [10]

Answer:

FE = 28 and YZ = 28

Step-by-step explanation:

In similar triangles the ratios of corresponding sides are equal.

(4)

$\frac{BC}{FG}$ = $\frac{BD}{FE}$ , substitute values

$\frac{39}{4x+2}$ = $\frac{42}{5x-2}$ ( cross- multiply )

39(5x - 2) = 42(4x + 2) ← distribute parenthesis on both sides

195x - 78 = 168x + 84 ( subtract 168x from both sides )

27x - 78 = 84 ( add 78 to both sides )

27x = 162 ( divide both sides by 27 )

x = 6

Thus

FE = 5x - 2 = 5(6) - 2 = 30 - 2 = 28

(5)

$\frac{ST}{SZ}$ = $\frac{RT}{YZ}$ , substitute values

$\frac{40}{35}$ = $\frac{3x-7}{2x+2}$ ( cross- multiply )

35(3x - 7) = 40(2x + 2) ← distribute parenthesis on both sides

105x - 245 = 80x + 80 ( subtract 80x from both sides )

25x - 245 = 80 ( add 245 to both sides )

25x = 325 ( divide both sides by 25 )

x = 13

Thus

YZ = 2x + 2 = 2(13) + 2 = 26 + 2 = 28
