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.
Answer:

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)
