Using Pythagoras’ theorem a2 + b2 = c2 you can find out the third (longest) side. (6x6) + (8x8) = 100 (the square root of 100 is 10) so ur final sum is 6+8+10 = 24 mm

1. The entire fraction is negative if the numerator or denominator are negative.

if both parts of the fraction were negative, the entire fraction would be positive (- / - = +)

2. Of course, although most teachers ask you to put the negative sign in the fraction as a whole (before the fraction line) or in the numerator. never leave a fraction with two signs. in this case, if it has two signs and they are different, the whole fraction is NEGATIVE

3) No. the whole fraction is POSITIVE only if both the numerator and the denominator have the same sign, + + or - -

The sum of and 7x2 is 10x2
Tems11 [23]

<u><em>Answer:</em></u>

The missing term is 3x²

<u><em>Explanation:</em></u>

Addition and subtraction can only take place between like terms.

<u>For two terms to be like</u>, both the variable and its degree must be the same in both terms

<u>Now, consider the given terms:</u>

First term is 7x² has the variable x with degree 2

The resulting term is 10x² has the variable x with degree 2

This means that the missing term is ax²

We need to get the value of "a"

<u>This is done as follows:</u>

ax² + 7x² = 10x²

x²(a+7) = 10x²

a+7 = 10

a = 10-7

a = 3

Therefore, the missing term is 3x²

Hope this helps :)
