Answer:
Width = 14m
Step-by-step explanation:
width = w
length = w - 6
area: w(w-6) = 112
w^2 - 6w = 112
14 x 14 = 196
6 x 14 = 84
196 - 84 = 112
70/28 = x/250
this however is not an equation it is a proportion so you would not be able to solve using systems of equations but you could use cross multiplication to solve this problem as well
24=-v/3
24 * 3= -v
72 = -v
v = -72
<span>Trinomial Ax^2 + Bx + C is perfect square if:
A > 0
C > 0
B = ±2√A√C
36b^2 − 24b − 16
C < 0
4a^2 − 10a + 25
2√A√C = 2*2*5 = 20,
B = −10
16x^2 + 24x − 9
not perfect square,
C < 0
4x^2 − 12x + 9
perfect square:
A>0,
C>0,
2√A√C
= 2*2*3
= 12
= -B
= (2x − 3)^2

Answer:
Below in bold.
Step-by-step explanation:
The hexagon is made up of 6 equilateral triangles.
So the Base = 12 cm.
Height a = 12 cos 30 = 10.392 cm
So area of 1 triangle = 1/2 * 12 * 10.392 cm^2
- and total area = 6 * 1/2 * 12 * 10.392
= 36 * 10.392
= 374.11 cm^2 to the nearest hundredth.
