Hello from MrBillDoesMath!
Answer:
Choice A, 1/4
Discussion:
Consider the perfect square
(x + a)^2 = x^2 + (2a)x + a^2
The constant term (a^2) equals 1/2 the coefficient of x (i.e. 2a), squared.
Let's apply this idea to x^2 + x
x^2 + x = => as 2 * 1/2 = 1
x^2 + ( 2 * 1/2)x =
( x^2 + (2* 1/2)x + ( 1/2) ^2 ) - (1/2) ^2 =
as constant term to add is 1/2 coefficient of x (that is, 1/2) and
(1/2)^2 - (1/2)^2 = 0
(x + 1/2) ^ 2 - (1/2)^2
In other words add the constant (1/2)^2 = 1/4, which is Choice A.
Thank you,
MrB
Answer:
in my opinion i think that the answer is c
So for CE, you add CD and DE together = CE.
4x+8+27=6x
4x+35=6x
4x-6x=-35
-2x=-35
x=17.5
Answer is the second one: CE=17.5
For ST, you just add SM and MT.
27+58=85
ST=85
It actually depends
One person is $6
Parking is $12
If you want to count the price for one person it is $6
If you want to count the price plus PARKING it would be $18
Answer:
it would be $98 for the whole class
Step-by-step explanation: let me know if you have to show your work so i can tell you how i did it :) .
