Answer:

x^{2} +11x-10

Step-by-step explanation:

(13x^{2} +9x-4)-(12x^{2} -2x+6)

Remove the brackets and multiply the minus sign through all the numbers in the second polynomial

13x^{2} +9x-4-12x^{2} +2x-6

Rearrange in the highest order

13x^{2} -12x^{2} +9x+2x-4-6

Simplify

x^{2} +11x-10

Seven less than 5 times a number is 62. What is the number. (Explain)
Marrrta [24]

7-5*14=62

The equation above is how you would write it with a variable.

The number is 14.

This is because if you do 14 times 5, the answer is 70. Then If you subtract from that, it would be 62.

You can also do 62+7, which is 70, and then divide that by 5 and you will still get 14.
