3x^2 + 9x - 4
3x^2 + 9x = 4
3(x^2 + 3x) = 4
Therefore, a = 3
The algebraic property is: Associative Property of Multiplication, which states that:
When three real numbers are multiplied, it makes no difference which two are multiplied first.
(a * b) * c = a* (b * c)
The same goes with your given problem, where 3*(x * y) = (3 * x) * y
Answer:
An object and its reflection have the same shape and size, but the figures face in opposite directions. The objects appear as if they are mirror reflections, with right and left reversed. A reflection can be seen, for example, in water, a mirror, or in a shiny surface.
Step-by-step explanation:
4 * side^2 = diagonal1 ^2 + diagonal2 ^2
4 * side^2 = 24^2 + 10^2
4 * side^2 = 576 + 100
4 * side^2 = 676
side^2 = 169
side = 13
So, the perimeter of this rhombus = 4 * 13 = 52 cm
Since 0.8 is the tenths place, and it is rounded from .799, it is to the tenths place. If the answer was written as .80, it would be to the hundredths place, as that would specify more accuracy in this answer.
