K = 4pq^2
k/4p = q^2
0.5(k/p)^1/2 = q
x= +7 or x=2-7 let me know if you need an explanation <3
Answer:
x=27, y=18
Step-by-step explanation:
Angle CB is 128, which means angle AC is 72. We can confirm angle O is also 72, since the lines are straight. Angle AM is 27, because AN is a right angle. 63+72+27= 162 180-162=18 Angle ND is 18.
Answer:
m=1
Step-by-step explanation:
Answer:
9x^2 -49
Step-by-step explanation:
We recognize that this is of the form
(a+b)(a-b) = a^2 - b^2
3x = a and 7 =b
(3x)^2 - 7^2
9x^2 -49
