Answer:

Choice A

Step-by-step explanation:

I would recommend starting off by using the distributive property.

(7x + 5)(2x³ - 4x² + 9x - 3) = 7x(2x³ - 4x² + 9x - 3) + 5(2x³ - 4x² + 9x - 3)

then simplify

= (14x^4 - 28x³ + 63x² - 21x) + (10x³ - 20x² + 45x - 15)

Now add it all together

= 14x^4 - 18x³ + 43x² + 24x - 15

The answer is choice A

Step-by-step explanation:

These are similar triangles, so the ratio of their sides is the same for each side.

AB = 8 and BD = 10

So, the ratio is 8:10 or 4:5

Because the triangles are similar....

The ratio of AC:CE is also 4:5

12:15 = 4:5

So, 12 is the answer!
