Answer:
Step-by-step explanation:
Use Pythagorean theorem.
c^2 = a^2+b^2
c^2 = 4^2+6^2
c^2 = 16+36
c^2 = 52
c = √52 = 7.21
Answer:
The proposed equation is solved as follows:
2X + 7 = 21
2X = 21 - 7
2X = 14
X = 14 / 2
X = 7
The value of X is 7.
A first degree equation is an algebraic equation in which each term is either a constant or a product of a fixed term on a single variable. Therefore, this equation is a first degree one, since it only has a single variable, which is X.
you can conclude that lines A and B are parallel to each other
Answer:
A=6
Step-by-step explanation:
If the area is enclosed by x(0,4) and y(3)
That means the area is a triangle
h(height) =3 b=4 c**2=a**2+b**2 c=5
The area of an equlateral triangle is A=h*b/2
A=3*4/2=12/2
