Answer:
22. Perimeter = 52 units
Area = 160 Square Units
23. Notation form : 
Standard Form : 200000
Step-by-step explanation:
22.
The formula for perimeter is
P = 2 (length + Width )
= 2 ( 2x+3x+1)
= 2(5x+1)
The Formula for Area of a rectangle is
A= length x width
A= 
A=
Now we have to find the Perimeter and Area for x = 5
P = 2(5 x 5 +1)
P= 2(26)
P=52 units
A= 6 x 5 x 5 + 2 x 5
A= 150 + 10
A= 160 square units
23.
A. By using rule of exponents , we can determine that both the results will be same.

Standard notation
Answer:
(0, 6)
explanation:
- original coordinates of C: (5, -6)
if reflected over x-axis, then use the formula: (x,y) → (x, -y)
then if translated -5 horizontally, there will be change in x axis
- new coordinates: (5-5, 6) → (0, 6)
Answer:
The coordinate of point M = (-6,7)
Explanation:
The Median of a triangle is a line segment from a vertex to the midpoint of the opposite side of a triangle.
Given: 
has vertices T(3,6) , R(-3,10) and E(-9,4).
Here, line TM is a median of triangle TRE where M is the midpoint of RE.
The midpoint of M of the line segment from R(-3,10) to E(-9,4) is;
M = 
Therefore, the coordinate of point M is, (-6,7).
The equation is 4 meatballs for every adult and 3 for every child. Replace a and c and solve:
M = 4(20) + 2(8)
M = 80 + 16
M = 96
They need 96 meatballs.
Answer:
its 2 1/4
Step-by-step explanation:
1/2x2 is 1 whole. 3/4 plus 1/4 is 2 wholes. plus 1/4 which is 2 1/4.
