Answer:

Step-by-step explanation:

Given that the triangles are similar then the ratios of corresponding sides are equal, that is

$\frac{AB}{DE}$ = $\frac{BC}{EF}$ , substitute values

$\frac{35}{5}$ = $\frac{42}{x}$ ( cross- multiply )

35x = 210 ( divide both sides by 35 )

What's an equivalent equation for -5(3-2x)

kobusy [5.1K]

Answer:

-15 + 10x

10x - 15

(either one works)

Step-by-step explanation:

Ok.

Multiply -5 by 3 and -2x.

(-5)(3) = -15

(-5)(-2x) = +10x

Add those together:

-15 + 10x

10x - 15

468=40x+18(x-3)
