Answer:
Let's simplify step-by-step.
3x2+9x+6−(8x2+3x−10)+(2x+4)(3x−7)
Distribute:
=3x2+9x+6+−8x2+−3x+10+(2x)(3x)+(2x)(−7)+(4)(3x)+(4)(−7)
=3x2+9x+6+−8x2+−3x+10+6x2+−14x+12x+−28
Combine Like Terms:
=3x2+9x+6+−8x2+−3x+10+6x2+−14x+12x+−28
=(3x2+−8x2+6x2)+(9x+−3x+−14x+12x)+(6+10+−28)
=x2+4x+−12
Answer:
=x2+4x−12

Answer:
Step-by-step explanation:
<u><em>Answer:</em></u>
One kilometer is
miles
<u><em>Explanation:</em></u>
<u>To convert a decimal to a fraction:</u>
1- Write the decimal as a fraction whose denominator is 1
2- Multiply both numerator and denominator by multiples of 10 to eliminate the decimal point
3- Simplify the fraction you have
<u>Now, for the given problem:</u>
<u>The given decimal is 0.62, following the above steps:</u>
<u>Step 1: </u>

<u>Step 2:</u>
We have two digits after the decimal point, so to eliminate the decimal point, we will multiply the numerator and the denominator by 100

<u>Step 3:</u>
We can note that, in the fraction obtained from step 2, both the numerator and the denominator are divisible by 2, so we simplify as follows:
