Answer:
Length = 40 cm
Width = 16 cm
Step-by-step explanation:
Length = x
Width = 1/2x -4
2 times length + 2 times width = perimeter
2x + 2(1/2x - 4) = 112 cm
2x + 2/2 x - 8 = 112 cm
2x + x = 112 + 8
3x = 120
x = 120/3
x = 40
Width = 40/2 - 4
Answer:
x < 3
Step-by-step explanation:
Divide both sides by 2.
(2x)/2 < 6/2
x < 3

An inequality is solved the same way an equation is solved, with one exception. If an operation is performed that changes ordering, then the comparison symbol is reversed. The usual case is multiplication or division by a negative number:
2 > 1
-2 < -1 . . . . both sides multiplied by -1
2, –2.2, 2.42, –2.662, 2.9282, …
5, 1, –3, –7, –11, …
–3, 3, 9, 15, 21, …
–6.2, –3.1, –1.55, –0.775, –0.3875, …
From the given options
options I, III and IV are Arithmetic sequences.
Given :
we are given with sequences. we need to check which one is arithmetic sequence.
A sequence is arithmetic when the consecutive terms have common difference.
Lets check one by one
Its arithmetic because common difference is same 3.6
2, –2.2, 2.42, –2.662, 2.9282, …
-2.2-2=-4.2
2.42+2.2=6.62
Its not arithmetic
5, 1, –3, –7, –11, …
1-5=-4
-3-1=-4
-7+3=-4
-11+7=-3
Common difference is -4. So it Arithmetic
–3, 3, 9, 15, 21, …
3+3=6
9-3=6
15-9=6
Its Arithmetic
–6.2, –3.1, –1.55, –0.775, –0.3875, …
-3.1+6.2=3.1
-1.55+3.1=1.55
Its not Arithmetic
So, options I, III and IV are Arithmetic sequences.

Step-by-step explanation:
The midpoint of the line is the point that divides in two halves of the same length.
Reasons:
The given parameters are;
The midpoint of AB in parallelogram ABCD = E
The midpoint of DC = F
Point of intersection of EF and DB = Point G
Required:
To prove that point G is the midpoint of EF.
Solution:
Statement Reason
1. m∠BDC ≅ m∠ABD 1. Alternate angles theorem
2. m∠DGF ≅ m∠BGE 2.Vertical angles theorem
3. = 3. Opposite sides of a parallelogram ABCD
4. ≅ 4. Definition of midpoint of DC
5. = 5. Definition of congruency
6. + = DC 6. Segment addition property
7. + = DC 7. Substitution property
8. 2· = DC 8. Addition
9. = 0.5· = 9. Division property
Similarly;
10. = 0.5· = 10. Division property
11. 0.5· = 0.5· 11. Multiplication property of equality
12. = 12. Substitution property
13. ΔDFG ≅ ΔBGE 13. Angle-Angle-Side rule of congruency
14. ≅ 14. CPCTC
15. = 15. Definition of congruency
16. Point G is the midpoint of 17. Definition of midpoint

Answer:
GF = GE that prove G is the mid-point of EF
Step-by-step explanation:
In the Parallelogram ABCD
∵E is the mid-point of AB
∵F is the mid-point of CD
∵AB = CD opposite sides in the parallelogram
∴EB = DF⇒(1)
∵AB // CD opposite sides in the parallelogram
∴m∠EBD = m∠FDB alternate angles ⇒(2)
∵BD intersects EF at G
∴m∠BGE = m∠DGF vertically opposite angles ⇒(3)
By using (1) , (2) and (3) you can prove:
ΔBGE is congruent to ΔDGF ⇒ AAS
∴GF = GE
∴G is the mid-point of EF
