The answer is -4x+64+2x^2

5x+8squared-9x+2xsquared simplifies to 

-4x+64+2xsquared. You must solve for x to figure out the total. But in order for that to happen, you must cancel each other out. Like an equation problem. 

2xsquared stays the same because there are no other numbers that have a #variable&exponent, therefore, it does not combine with anything else.

Show two ways to multiply 2/15 x 3/20. Then tell wich way is easier and justify your choice
Radda [10]

The easier way to multiply 2/15 by 3/20 will simply be by multiplying the numerators and denominators.

In order to multiply 2/15 x 3/20, we can simply multiply the numerator and the denominator. This will be

= 2/15 × 3/20

= 6/300

= 1/50

Also, in order to multiply the fractions, we can change them to decimal first. This will be:

= 2/15 × 3/20

= 0.133 × 0.15

= 0.01995

In conclusion, multiplying the numerators and denominators is easier and faster.
