Answer:
3.6 m
Step-by-step explanation:
Because the triangle is a right triangle, we can use the pythagorean theorem:
a^2 + b^2 = c^2 (a and b are the legs of the right triangle, and c is the hypotenuse)
6^2 + b^2 = 7^2
36 + b^2 = 49
b^2 = 13
b = 3.6 m
Answer: - 4/3
0 cannot be a negative, so if it 0,0 between -4,3 it obviously -4/3
1/-2
y = x^2 + 12x + 27
or
x^2 + 12x + 27 = 0
(x + 9)(x + 3) = 0
x = -3, -9
Cathode Ray tube is the answer I think
