The shapes are irregular and is formed by a octagon and a rectangle (square kinda = rectangle)

But given your multiple choice...

1) Shape 1 and 2 isn't congruent so false.
2) Shape 1 and 2 don't share the same coordinates because of a prior translation so false.
3) Shape 1 and 2 isn't congruent so false.
4) Shape 1 could be translated onto shape 2, but it still would not be congruent, so true.

Therefore the 4th one is true.

Answer:

Step-by-step explanation:

Given that:

sin2xcos x + cos2xsin x = -1

Recall that;

SInAcosB + cosASinB = SIn (A+B)

SIn (2x +x) = -1

Sin (3x) = -1

$x = \bigg [\dfrac{Sin ^{-1} (-1)}{3} \bigg ]$

$x = \dfrac{\pi}{2} + \dfrac{2 \pi \ k}{3}$

$x = \dfrac{\pi}{2}, \dfrac{7 \pi}{6}, \dfrac{11 \pi}{6}$

Find the length of LK

ehidna [41]

Since JN = NK, this means that JK has been split into two equal pieces

This points to the fact that the smaller triangle is half of the larger triangle in terms of side lengths

MN = 14 which means LK is twice as long, so LK = 2*MN = 2*14 = 28

In summary,

LK = 28

Five more than a half number is 6. find the number.

Artyom0805 [142]

First write the equation:
1/2x + 5 = 6

Then subtract five from both sides:

1/2x = 1

Multiply both sides by 2:

x = 2

Mandy used the input and output in this table to write ratios. She concluded that because that they are not all equivalent, this

wolverine [178]

The problem is stating that Mandy found the ratio between input and output of many points on the graph, which are displayed by the fractions. Mandy's conclusion was that they were not equivalent, meaning they were different and that is why the function is not proportional. Mandy's conclusion is wrong, the relation is proportional. If we take all the functions we have:

$\frac{5}{1}=\frac{10}{2}=\frac{25}{5}=\frac{50}{10}$

Where the input is the denominator and the output is the numerator we will have a ratio of "5". Mandy's mistake was to invert the last fraction, she inserted the output in the denominator, this is why she said the were different.
