The given expression is : (4x – 7.2) + (-5.3x-8)
Simplify :
Open the brackets :
(4x – 7.2) + (-5.3x-8) = 4x - 7.2 - 5.3x - 8
Arrange the variable and constant terms together :
(4x – 7.2) + (-5.3x-8) = 4x - 5.3x - 8 - 7.2
Solve the variable and constant terms together :
(4x – 7.2) + (-5.3x-8) = - 1.3x - 15.2
Since, the variable and constant term can not solve together so the above equation is the simplest form:
(4x – 7.2) + (-5.3x-8) = - 1.3x - 15.2
Answer : (4x – 7.2) + (-5.3x-8) = - 1.3x - 15.2

Answer is -6. Whatever number is closer to 0 when negative will always be bigger. Good luck!
A = bh
A = (22)(18)
A = 396 m²
A = ¹/₂h(b₁ + b₂)
A = ¹/₂(8)(16 + 12)
A = ¹/₂(8)(28)
A = ¹/₂(224)
A = 112 cm²
P = 2l + 2w
20 = 2l + 2(4)
20 = 2l + 8
- 8 - 8
12 = 2l
2 2
6 = l
C = 2πr
C = 2(3.14)(8)
C = 2(25.12)
C = 50.24 in
A = πr²
A = (3.14)(3)²
A = (3.14)(9)
A = 28.26 m²
