Use the factoring to find the solution to the following equation

Step-by-step explanation:

13x^2 + 56x + 75 = 4x^2 - 10x - 46

You need to first combine like terms, so subtract 4x^2 from both sides,

9x^2 + 56x + 75 = -10x - 46

then add -10x to both sides

9x^2 +66x + 75 = -46

then add -46 to both sides

9x^2 + 66x + 121 = 0

Then use the quadratic formula,  

So

a = 9

b= 66

c = 121

That simplifies to

Which simplifies to

Which simplifies to

or

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have
