Answer:
2(n+3) - 6 = 2n
Step-by-step explanation:
Let n stand for lonnie's starting number.
Kristy asks to add 3 to the number. It will become (n+3)
Now he ask to multiply the sum by 2. It will become 2(n+3).
Finally, he ask to subtract 6. It will become 2(n+3) - 6
The expression is : 2(n+3) - 6.
We can simplify it as follows :
= 2n+6-6
= 2n
Hence, the required expression is 2n.
0.24 should be your answer

Length=2(x-1)
Width=5
Area=length*width = (2(x-1))(5) = (2x-2)(5) = 10x-10

His reasoning is illogical because whether or not an expression has a term that is being subtracted isn't relevant; technically there are an infinite amount of ways to represent a value. Plus you can just compute the expressions and see that they're equal:
6x-2x+4 = 4x+4
4(x-1) = 4x+4
30
The two expressions are equal because when you compute the expression 4(n+3)-(3+n) , you get 3n+9:
4(n+3)-(3+n) = 4n+12-3-n = 3n+9
31
The two expressions are equal because when you compute the expression 2(2n-1), you get 4n-2.
2(2n-1) = (2)(2n)+(2)(-1)=4n-2

5(g+14)=(5)(g)+(5)(14)=5g+70
The expressions aren't equal as 5(g+14) equates to 5g+70 and 5g+70≠5g+14.
Answer:
so the labelled angles are 30 and 90, but it only shows one 90. In fact there are 4 angles of 90. The marked 90 then the vertical angle and the complementary angles. All triangles equal 180 so the given 30 and 90 are taken from the 180.
180 -30-90= 60
But y is the opposite of the 30 which makes y=30
so that leaves x = 60
y=30 and x=60
