Answer:
x=1
Step-by-step explanation:
-31 - 4x= -5 - 5 (1+5x)
-31-4x=-5-5-25x
Separate the different variables and solve.
-31+5+5=4x-25x
-31+10=-21x
-21=-21x
x=1
Answer: 3 x 6
18 yd²
Step-by-step explanation:
The area of quadrilateral ABCD is 2 spare units, It is obtained from the given diagram.
Step-by-step explanation:
The given is,
Quadrilateral ABCD
Step:1
Let,
Area of Quadrilateral ABCD = Area of ΔABC +Area of ΔADC.....(1)
From ΔABC,
Height of ΔABC, - 1
Base of ΔABC, - 2
From ΔADC,
Height of ΔADC, - 1
Base of ΔADC, - 2
Step:2
Area of triangle is,
For ΔABC,
=
= 1 square units
For ΔADC,
=
= 1 square units
Step:3
From equation (1),
= 1 + 1
= 2 square units
Result:
The area of quadrilateral ABCD is 2 spare units, It is obtained from the given diagram.
$31.50 is the correct answer
