F(g(x)= x+4
f(x+4)= 5(x+4)-9
=5x+20-9
=5x+11
g(f(x)= 5x-9
g(5x-9)=5x-9+4
=5x-5

Given the figures are similar, calculate the perimeter of the ABCDE.

Vsevolod [243]

Let the length of side AB be $x$, then

$\cfrac{x}{2}=\cfrac{12}{4}\Rightarrow4x=24\Rightarrow x=\cfrac{24}{4}=6.$

Therefore, the perimeter of ABCDE is 2(12) + 2(4) + 6 = 24 + 8 + 6 = 38 in.

I, so confused please help me asap!

Quadrilaterals are plane shapes that are bounded by four straight sides. Thus, the required answers to the questions are:

46. True. Other examples include kites, rhombus, etc.

47. False.

46. When a plane shape is bounded by four straight sides of equal or different lengths, it is called a quadrilateral. Examples include trapezium, kite, rhombus, rectangle, square, etc. Each of these examples has individual properties.

Thus the required answer to question 46 is; True. It can be observed that with respect to their individual properties, other quadrilaterals which have a pair of opposite angles to be equal include: kite, rectangle, rhombus, etc.

47. A ray segment is a given line that points or heads in a specific direction. So that the direction in which the ray moves is very important.

Thus in the given question, the required answer is; False. This is because the two given rays are moving in opposite directions. Though the two rays may have the same length of the segment.

Evaluate. Pay close attention to all brackets and signs. [-2.99] + [2.99]

Elena-2011 [213]

Alright, so [-2.99] is -2.99, and [2.99] is 2.99, so -2.99+2.99=0
