After a translation, the measures of the sides and angles on any triangle would be the same since translation only involves changing the coordinates of the vertices of the triangle.
After a rotation, the measures of the sides and angles of a triangle would also be the same. Similar to translation, the proportion of the triangle is unchanged after a rotation.
After a reflection, the triangle's sides and angles would still be the same since reflection is a rigid transformation and that proportion of the sides and angles are not changed.

Answer:

(x + 3) ( x - 6)

Step-by-step explanation:

x² - 3x - 18

x² - 6x + 3x - 18

x(x - 6) + 3(x - 6)

(x + 3) ( x - 6)

Answer:

For question 26 the answer is ( 9^210 )

For question 27 the answer is ( 24 )

Step-by-step explanation:

For question number 26: try on the scientific calculator the equation you have pictured it will give you a very long number beginning with 《 2459953978》

Then put the the 9^210 on the calculator and click ( =) if it didn't work try clicking S》D then you will get the same long number Count at least the first 6 numbers for assurance

For question number 27 :The volume of a right cone is given by 

 $v = \frac{1}{3} \pi \ \: {r}^{2} h$ 

 Here, you only know the value of one of the variables, V, so you'll need to use the information in the question to somehow write r and h in terms

If the cone is three times as wide at the base as it is tall, then call the diameter 3x and the height of the cone one-third of that, or x. The volume formula calls for the radius, which is half the diameter, or

 $\frac{3x}{2}$ 

Substitute these values into the formula and solve for x:

$384\pi = \frac{1}{3} \pi {( \frac{3}{2}\pi) }^{2} x \\ 384 = ( \frac{1}{3} )( \frac{9}{4} {x}^{2} )x \\ 384 = \frac{3}{4} {x}^{3 } \\ 512 = {x}^{3 } \\ \sqrt[3]{512} = x \\ 8 = x \\$

The question asks for the diameter of the base, which is 3x = 3(8) = 24.
