7 0

Answer:

x = - 4, x = 6

Step-by-step explanation:

To find the x- intercepts let y = 0 , that is

- 3(x + 4)(x - 6) = 0

Equate each factor to zero and solve for x

x + 4 = 0 ⇒ x = - 4

x - 6 = 0 ⇒ x = 6

1.Find the area of a trapezium with parallel sides of

Nana76 [90]

Answer:

The area of the trapezium is $74.8\ cm^2$

Step-by-step explanation:

Area of a trapezium:

$\displaystyle A=\frac{b1+b2}{2}h$

This formula is valid if b1 and b2 are parallel and h is perpendicular to both.

Since the trapezium given in the problem satisfies those conditions, we use the formula with:

b1=15 cm

b2=7 cm

h=6.8 cm

$\displaystyle A=\frac{15+7}{2}\cdot 6.8$

$A=74.8\ cm^2$

The area of the trapezium is $74.8\ cm^2$
