Answer:
Step-by-step explanation:
You need to know this indice rule:
If you multiply two terms with the same base, then add their powers and multiply their coefficients.
: Here we have to multiply each term in the first pair of brackets by the term in the second pair of brackets.
So we can split this into parts:
Now using the rule above expand the brackets:
: Notice how since so .
: Be careful with negatives, two negatives make a positive.
Now add them all together:
A scale factor (<em>k</em>) is a number by which the size of any geometrical figure or shape can change:
• If the image is ,enlarged,, then the ,scale factor is more than one (,k > 1,).
,
• If the image is ,contracted,, then the ,scale factor is less than one (0 < k < 1).
Then, the smaller the scale factor, the smaller the figure. In our case, the options given are:
And if we evaluate the size of the dilated figures, we can see that:
[tex]BA is the biggest while B is the smallest.
Then we can suppose the scale factors.
