Answer:
155 degrees
Step-by-step explanation:
Every 4 angled shape will equal 360
45+130+30+x=360
205+x=360
155=360
Correct option is B. Area of rectangle is
We know that area of rectangle = Length × Width
We are given,
Length = 12y - 5
Width = 2y
So, area of rectangle = (12y - 5) × (2y)
= ×
= (12y × 2y) - (5 × 2y)
=
<h3>What are
algebraic equations?</h3>
An algebraic equation can be defined as a mathematical statement in which two expressions are set equal to each other. The algebraic equation usually consists of a variable, coefficients and constants. Also Check: Algebraic Expressions. In simple words, equations mean equality i.e. the equal sign.

The inequality negative 3 and one-half greater-than negative 4.5 or -3.5 > -4.5 is true.
<h3>What is inequality?</h3>
It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than known as inequality.
We have inequalities given:
or
1.5 > 2.5 (false)
1/2 > 0.5
0.5 > 0.5 (false)
-2.5 > -1.5 (false)
-3.5 > -4.5 (true)
Thus, the inequality negative 3 and one-half greater-than negative 4.5 or -3.5 > -4.5 is true.
