5/10 = 8/16
Answer: SECOND OPTION
Step-by-step explanation:
You must find the ratio of the sides of the triangle, as following:
Therefore, the ratio of the areas is:
Now you must multiply the area of the larger triangle by the ratio obtained above, therefore, you have that the result is:
≈
14. 2x-1 = 0, x+7=0
x = 1/2, x = -7
15. x^2 + 3x - 10 = 0
(x + 5)(x - 2) = 0
x = -5, x = 2
16. x^2 - 25 = 0
(x-5)(x+5)
x = 5, x = -5
