☺ 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

I hope, this will help you.☺
Thank you______❤

38: it's a right triangle
39:
area:


circumference:

Answer:
B. 1.7 in
Step-by-step explanation:
Divide the triangle into 2 congruent right angle triangles
With hypotenuse: 2
Base: 2/2 = 1
Using pythagoras theorem
2² = 1² + h²
h² = 3
h = sqrt(3)
h = 1.732050808
Answer:
The value of x is 8/5
Step-by-step explanation:
(35/6)x + (8/3) = 12
(35/6)x = 28/3 (cross multiplication)
105x = 168
x = 8/5
