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)
=
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.

we know that
The measure of the interior angle is the half-sum of the arcs comprising it and its opposite.
so
<u>Find the measure of the angle LAM</u>
m∠LAM is equal to
<u>Find the measure of the angle MAJ</u>
we know that
m∠LAM+m∠MAJ=° ------> by supplementary angles
m∠MAJ=
m∠MAJ=°
therefore
<u>the answer is</u>
The measure of the angle MAJ is
An equation of the form ax+by+c=0, where x, y are variable, and a, b, c are numbers, is called a "linear equation"
the reason we call it linear, is that all solutions (x, y) to this equation, when plotted in the x-y axis, form a line.
To draw this line, 2 points are enough, that is 2 solutions (x, y) of the equation.

-2x+5y-10=0 is a linear equation (a=-2, b=5, c=-10)
to find 2 solutions, we set x or y any value we want, and solve for the other
for example:
let x=0,
then
-2x+5y-10=0 becomes 5y-10=0, so y=2
this gives us the solution (0, 2)
another example; set y=0
then -2x+5y-10=0 becomes -2x-10=0; -2x=10 so x=-5
thus another solution is (-5, 0)
Draw these 2 points, and join them with a line, as shown in the figure.
