Use the foil method to multiply out the expressions. Then solve for x by first combining like terms and then using inverse properties
8x^5 +4x^2 - 12
= 4(2x^5 + x^2 -3)
answer is A
Circumference of a circle is the distance around the circle. This can be found by using the equation below
2*pi*radius
Our diameter, as shown, is 9cm. Since radius is half of the diameter, our radius is 4.5cm.
Therefore, our circumference is...
2 * pi * 4.5 = 9pi cm total
4.5 is the answer
Divide 49 from both sides
220.5 / 49 = 4.5
The diagram of rhombus JKLM is shown in the diagram below
A rhombus is a quadrilateral with four equal sides and its diagonals intersect perpendicular to each other (makes 90° angles). Opposite angles are equal (the same with a parallelogram). Each diagonal bisects the angle at J, K, L, and M equally
If angle JKL is 104°, the measurement of angle JKN is 104÷2=51°
