What is the product of 3x+4 and 6x2-4x+2

18x³ + 36x² + 22x + 8

Step-by-step explanation:

Multiply 3x + 4 times each term in the latter equation. 6x² times 3x + 4 is 18x³ + 24x².

3x + 4 times 4x is 12x² + 16x.

3x + 4 times 2 is 6x + 8.

Combine like terms to get 18x³ + 36x² + 22x + 8

10.416 meters per second

step-by-step explanation:

distance=1 00 meters

time= 9.6 seconds in decimal form or 9 3/5 as a mixed number

average speed= 100/9.6

=10.416 meters per second or 10 52/125 as a mixed number.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
