The answer to this question of yours is B
Answer:
x= -6,1
Step-by-step explanation:
The Given Equation is ...............(i)
Now we Know that Quadratic formula is
............(ii) and
..............(iii)
In the given equation
a= 1 , b= 5 , c= -6
For the first value of x Putting these in equation (ii) gives
x= 1
so one value of x = 1
Now for the second value we will put the values in eqaution (ii) which gives us
x= -6
so second value of x = -6
So the solution to equation is x= -6,1
Answer:
Q7. 11.3 inches (3 s.f.)
Q8. 96.2 ft
Q9. 36.4cm
Step-by-step explanation:
Q7. Please see attached picture for full solution.
Q8. Let the length of a side of the square be x ft.
Applying Pythagoras' Theorem,
Thus, the perimeter of the square is
Q9. Equilateral triangles have 3 equal sides and each interior angle is 60°.
Since the perimeter of the equilateral triangle is 126cm,
length of each side= 126÷3 = 42 cm
The green line drawn in picture 3 is the altitude of the triangle.
Let the altitude of the triangle be x cm.
sin 60°=
(to 3 s.f.)
Therefore, the length of the altitude of the triangle is 36.4cm.
