Which term completes the product so that it is the difference of squares?

(−5x−3)(−5x+

−9
−3
3
9

3

Step-by-step explanation:

Note the general factorisation of a difference of 2 squares is

a² - b² = (a + b)(a + b)

Given

(- 5x - 3)(- 5x + ?)

Then ? = 3 so that the complete factors are

(- 5x - 3)(- 5x + 3)

6 meters

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
