If you are doing a multi step question that looks something like this: 23+(4)-4 or longer. You will have to use a formula called BEDMAS. It stands for brackets, exponents( which are little numbers on top of a number), then you deal with division, multiplication, addition, and subtraction. You will have to solve your equation in this order. If you don’t you will get another, answer.
Answer:



Step-by-step explanation:
Given
Similar Triangles: ABC and DEF



Required
Determine the sides of DEF
No options were given, so I will solve on a general terms.
Since both triangles are similar, then the following relationship exists.
DEF = ABC * n
i.e.

Where

Assume n = 2.
So, we have:







Assume 
So, we have:







So, the possible sides are:



Answer:
5a+1 1/2=4
a = 1/2
Step-by-step explanation:
Answer:
Y decreased by 23
Step-by-step explanation:
Subtract the y values:
-19 - 4 = -23
Y decreased by 23
