☺ Hello mate__ ❤
◾◾here is your answer...
i think right question is this
(3x − 7y)^2
ok now start solving:-
(3x − 7y)^2
=> (3x − 7y) (3x − 7y)
=> 3x(3x- 7y) -7y(3x-7y)
=>. 3x.3x - 3x.7y-7y. 3x + 7y.7y
=> 9x^2 -27xy +27xy + 49y^2
=> 9x^2 + 49y^2
so your correct ans. is 9x2 + 49y2

Answer:
About 588.7 mm^3
Step-by-step explanation:
The formula for the volume of a sphere is (4/3)*pi (or in this case 3.14)*r^3, where r is the radius.
We need the radius. We are given the diameter, 10.4.
The radius is half the diameter, so 10.4/2=5.2.
Use r=5.2 and put it into the formula:
(4/3)*3.14*5.2^3≈588.7
Answer:
The probability of the first draw is 100%, because the bead will be either red or white. For the second draw, a different color must be drawn.
So, if draw 1 is white, then the probability of draw 2 being red is 7/10. and if the first draw is red, then the probability of draw two being white is 5/10.
