To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the > sign and the answer on the other.

-7c + 6 > \( \frac{c}{-4} \)
-4 x (-7c + 6) > c
(-4 x -7c) + (-4 x 6) > c
28c - 24 > c
28c - 24 - c > 0
28c - c > 24
27c > 24
c > \( \frac{24}{27} \)
c > \(\frac{8}{9}\)

An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.

To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.

(7a)(3ab) - (2a²)(9b)
(7 x 3)(a x a x b) - (2 x 9)(a² x b)
(21)(a¹⁺¹ x b) - (18)(a²b)
21a²b - 18a²b
3a²b

To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.

8a⁹ - 5a⁹ = 3a⁹

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).
