The answer is B. (2 + x) + 3y.
The associative change happened when they just moved the parenthesis.
Hope this helps!
Answer: C (1.25, 10.25)
Step-by-step explanation:
The key lies in translating "1/10 percent." If the unknown number is n, then 0.001n = 10. Mult. both sides by 1000: n = 10000 (answer)
U write it as 1/6+1/6+1/6+1/6=4/6
Area of a triangle:
A= (1/2)(bh)
In this problem we are given:
A= 178.5

b= h+4 in
h= UNKNOWN ("h")
Plug in our values into the area equation and solve for "h":


(multiply each side by 2 to get rid of the 1/2)



(357/21=17)

(solve both inequalities separately)


( a negative height is not possible so, this answer is incorrect.)


Answer: base = (h+4)= (17+ 4)
b= 21 in h= 17inPlease comment with any further questions! :)
