Answer:
c
Step-by-step explanation:
the circle is moving like a clock ( clockwise)
Step-by-step explanation:
7x² + 9x² - x²
when you wrote the expression you used the "multiplication ×" and not "x".
anyway, when you have terms of the same variable of the same exponent, then the combination variable and exponent become an item. and the same items can simply be added in an expression.
this is similar to
7 apples + 9 apples - 1 apple
what would you do there ?
see ?
and the same we are doing now for the given expression : we are adding the terms up :
7x² + 9x² - x² = (7 + 9 - 1)x² = 15x²
and in the middle I gave you even the reason why we can do that.
please, let me know, if this is still unclear.

5b+10
Step-by-step explanation:
This can be solved using the distributive property. You multiply 5 by b to get 5b, and then 5 by 2 to get 10. This then gives you 5b+10
