2x-12x-4
Collect the like terms second.
-10x-4
Answer:
C. ABCD is a rhombus, but not necessarily a square.
Step-by-step explanation:
A parallelogram with adjacent sides congruent is a rhombus, which also happens to have perpendicular diagonals (that bisect each other). If the diagonals are different length, then the parallelogram is not a rectangle, so the rhombus is not a square.
Answer:
C. 120º
Step-by-step explanation:
so we know that the inside of a triangle is 180º and since all the measures are the same we can do 180/3 to find how much each angle is.
180/3 = 60º
now we also know that a straight line is equal to 180º and since we already have one angle, all we have to do is subtract 60 from 180.
180 - 60 = 120º
Answer:
The simplest form of the given expression is 7x³ + 5x² + x + 2
Step-by-step explanation:
(4x³ + 6x - 7) + (3x³ - 5x² - 5x + 9)
Group like terms together.
(4x³ + 3x³) + 5x² + (6x - 5x) + (-7 + 9)
Combine like terms.
7x³ + 5x² + x + 2
So, this will be your simplest form of the given equation.
Answer:
The formula for the volume of a cylinder is pi*r^2*h. ... The formula for the volume of a cone is 1/3*pi*r^2*h. Finally, we looked at spheres, like a basketball and the planets. The formula for the volume of a sphere is 4/3*pi*r^3.
So basically, they have alike formulas
