Question 3
Likurg_2 [28]

Answer:

27cm

Step-by-step explanation:

first, separate the 2 shapes you will find the area too. these would be the little 3 by 3 block sticking out on top, and the other piece.

to find the area, you have to do length times width.

you can start off with the 3 by 3 block. 3 times 3 = 9cm

next, you have to find the measurements of the rectangular shape. we know the width is 6cm. and the length of the whole shape is also 6cm. but we can take off the 3cm from the other shape. we now have 3cm leftover to be the length for the rectangle.

we can now find the area for the rectangle. 6 times 3 = 18cm.

last but not least, we can add the 2 measurements up to get the area of the whole shape. 9 + 18 = 27cm.

Find the GCF of the terms of the polynomial. 48x ^ 6 + 6x ^ 2 - 26x ^ 3
galben [10]

Answer:

2x^{2}

Step-by-step explanation:

Find the GCF of the numbers 48, 6 and 26.  

The largest number each can be divided by is 2, which is the GCF.

Find the GCF of x^{2}, x^{3}, x^{6}

The GCF is always the smallest exponent, so x^{2} is the GCF

Combine the two GCF for the answer

2x^{2}

There are 20 entries in the chess tournament. How many ways can they finish in first, second,
Romashka [77]

Answer:

6840

Step-by-step explanation:

Here, the order matters (1st, 2nd, and 3rd), so we need to use permutations.

There are 20 people who can get in first place.  After that, there are 19 people who can get in second place.  Finally, there are 18 people who can get in third place.  So:

20 * 19 * 18 = 6840
