To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.

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).

The area of a triangle is equal to ½ base x height:

a = ½bh
a = ½ x 9 x 5 = \( \frac{45}{2} \) = 22\(\frac{1}{2}\)

You need to find the value of b so solve the first equation in terms of z:

4b + z = 1
z = 1 - 4b

then substitute the result (1 - 4b) into the second equation:

3b - 6(1 - 4b) = 5
3b + (-6 x 1) + (-6 x -4b) = 5
3b - 6 + 24b = 5
3b + 24b = 5 + 6
27b = 11
b = \( \frac{11}{27} \)
b = \(\frac{11}{27}\)

A cube is a rectangular solid box with a height (h), length (l), and width (w). The volume is h x l x w and the surface area is 2lw x 2wh + 2lh.
