A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.

Parallel lines are lines that share the same slope (steepness) and therefore never intersect. A transversal occurs when a set of parallel lines are crossed by another line. All of the angles formed by a transversal are called interior angles and angles in the same position on different parallel lines equal each other (a° = w°, b° = x°, c° = z°, d° = y°) and are called corresponding angles. Alternate interior angles are equal (a° = z°, b° = y°, c° = w°, d° = x°) and all acute angles (a° = c° = w° = z°) and all obtuse angles (b° = d° = x° = y°) equal each other. Same-side interior angles are supplementary and add up to 180° (e.g. a° + d° = 180°, d° + c° = 180°).

You need to find the value of a so solve the first equation in terms of x:

-6a + x = 1
x = 1 + 6a

then substitute the result (1 - -6a) into the second equation:

4a - 6(1 + 6a) = -1
4a + (-6 x 1) + (-6 x 6a) = -1
4a - 6 - 36a = -1
4a - 36a = -1 + 6
-32a = 5
a = \( \frac{5}{-32} \)
a = -\(\frac{5}{32}\)

A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.

A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
