What expression is equivalent to 2(24x-18), 3(16x-12), 4(12x-9)

polet [3.4K]

Use the distributive property, which states:
a(b+c) = ab + ac
a(b-c) = ab - ac

2(24x - 18) = 2(24x) - 2(18) = 48x - 36

3(16x - 12) = 3(16x) - 3(12) = 48x - 36

4(12x - 9) = 4(12x) - 4(9) = 48x - 36

All of the expressions are equivalent to 48x - 36.

If polygons are similar ratio of sides will be same

$\\ \sf\longmapsto \frac{6}{14} = \frac{3}{x} \\ \\ \sf\longmapsto 6x = 14 \times 3 \\ \\ \sf\longmapsto 6x = 42 \\ \\ \sf\longmapsto x = \frac{42}{6} \\ \\ \sf\longmapsto x = 7$
