Answer:
The correct expression for the perimeter is 
see the explanation
Step-by-step explanation:
The complete question in the attached figure
Let
L ----> the length of rectangle
W ---> the width of rectangle
we know that
The perimeter of rectangle is equal to

In this problem we have


substitute the values



Simplify

so
Michelle didn't multiply the sum of length and width by 2
Hence verified!. Hope it's understandable and nvm that background lol.
Answer:
x=1 and y= 5
Step-by-step explanation:
To solve this, lets take the first equation and find the x value.
Because it is ordered in standard form, we need to convert to slope-intercept form, and isolate the y.
5x+4y=16
-5x -5x
4y=-5x+16
÷4 ÷4 ÷4
y=
+4
or
y=-1
+4
or
y= 5
Now that we have the y value, we can use this to find the x value by inserting it into either equation, since they both have y values in them. Going with the first one again, lets try it:
5x+4(
+4)=16
5x-5+16=16
5x+11=16
-11 -11
5x=5
÷5 ÷5
x=1 and y= 5
Answer:
You can use the ASA Postulate to prove the Angle-Angle-Side Congruence Theorem. A flow proof is shown below. If two angles and a nonincluded side of one triangle are congruent to two angles and the corresponding nonincluded side of another triangle, then the triangles are congruent.
