Your answer is 506.44.
multiply 662 x .10 now minus that answer from 662 to get 595.80
now multiply that by .15
now minus that by 595.80
gives you 506.43
Answer:
<h2><em><u>2x</u></em><em><u> </u></em><em><u>×</u></em><em><u> </u></em><em><u>2x</u></em><em><u> </u></em><em><u>×</u></em><em><u> </u></em><em><u>2x</u></em></h2>
Step-by-step explanation:

= <em><u>2x × 2x × 2x (In expanded notation form) (Ans)</u></em>
Distance formula : d = sqrt (x2 - x1)^2 + (y2 - y1)^2
(-5,8)(10,-7)
d = sqrt (10 - (-5)^2 + (-7 - 8)^2
d = sqrt (10 + 5)^2 + (- 15^2)
d = sqrt (15^2) + (-15^2)
d = sqrt 225 + 225
d = sqrt 450
d = 21.21
We can solve this using the FOIL method.
= (7x + 3)(7x - 3)
= (7x * 7x) + (7x * -3) + (3 * 7x) + (3 * -3)
= 49x - 21x + 21x - 9
= 49x - 9
