Assume they are right triangles, find the other side of the smaller triangle
2(57/8) = 14.25 sq/ft: (.5*14.25*8=57).
Find the other side of the larger triangle, using corresponding sides in
similar triangles
*14.25 = 24.9375

Find the area of the larger triangle
.5*14*24.9375 = 174.5625 sq/ft area of the larger triangle.

Margarita [4]

Answer:

\boxed{\mathrm{view \: explanation}}

Step-by-step explanation:

A) 3x²c² + 5xc² - 2c²

Factor c² from all terms in the expression.

c²(3x² + 5x - 2)

Factor 3x² + 5x - 2

c²(3x-1)(x+2)

B) x² + 6x + 9

x² + 3x + 3x + 9

Factor common terms.

x(x+3)+3(x+3)

Take x+3 common.

(x+3)(x+3)

C) x² - 9

x² -3²

Apply formula : a² - b² = (a+b)(a-b)

(x+3)(x-3)
