Answer:
-3x + 11
Step-by-step explanation:
The best method to solve this problem is using distributive property.
2(x + 3) = 2x + 6
5(x - 1) = 5x - 5
(2x + 6) - (5x - 5)
Open parenthesis, change the negative sign in the parenthesis to a positive sign because there is a negative sign in front.
2x + 6 - 5x + 5 = -3x + 11
Hope this helps :)
Answer:
We can represent a number in general by x . Halving a number means dividing it by two, so the expression that shows the half of a number is x2 , since you divide a number by two.
Step-by-step explanation:
(AB)^2 + (2 m)^2 = (8 m)^2, or
(AB)^2 + 4 m^2 = 64 m^2, or (AB)^2 = 60 m^2.
Taking the square root of both sides, (length of AB) = + 2sqrt(15) (answer)
I accidentally went too far, but I still solved your question... the answer is 9x^2 - 6x
