Answer:

2: 3, 4: 6, 6: 9, 8: 12 , 10: 15, 12: 18, 14: 21, 16: 24, 18: 27, 20: 30, 22: 33, 24:36, 26: 39, 28: 42, 30: 45, 32: 48, 34: 51, 36: 54, 38: 57

Step-by-step explanation:

The ratio 4: 6 can be simplified to 2:3 by dividing by 2 to each side of the ratio. After simplified to 2:3, you add the ration to itself to get the rest of the terms.

What is the product?<br> (-2x- 9y2 )(-4x-3)

lara [203]

Answer:

$36xy^2 + 8x^2 + 27y^2 + 6x$

Step-by-step explanation:

Use the FOIL method of multiplying binomials.

First term in each binomial: $-2x * -4x = 8x^2$

Outside terms: $-2x * -3 = 6x$

Inside terms: $-9y^2 * -4x = 36xy^2$

Last term in each binomial: $-9y^2 * -3 = 27y^2$

Now, rearrange the terms correctly. $36xy^2 + 8x^2 + 27y^2 + 6x$

This is our final answer, since it can not be simplified any more.
