Answer:
<h2><u>
=10b−40</u></h2><h2><u>
</u></h2>
Step-by-step explanation:
−10(4−b)
=(−10)(4+−b)
=(−10)(4)+(−10)(−b)
=−40+10b
<u>=10b−40</u>
Top right would be rhombus
Answer:
approximation is often useful when it is not a very good one
Answer:
Below in bold.
Step-by-step explanation:
Area = 30 + 12x and area is also = to width * length so we need to look for factors of 30 + 12x.
30 + 12x = 6(5 + 2x)
So 6 and 5 + 2x is one possible answer.
3 and 10 + 4x is another.
12 and 2.5 + x is another.
If we multiply these pairs together we see that the result is
30 + 12x in each case.
Answer:
Option C is the right answer.
Step-by-step explanation:
Given that:
Length of diagonal = 25 inches
Length of rectangle = 9 inches
Width of rectangle will be one of the two legs of right angled triangle and the diagonal will be the hypotenuse.
Using Pythagorean theorem;

Taking square root;

Therefore,
Option C is the right answer.
