Calculate the area of this trapezium.
6 cm
4 cm
5 cm
8 cm

15 square cm

Step-by-step explanation:

Hi ,

Dimensions of the Trapezium ,

Let a , b are two parallel sides ,

a = 6 cm,

b = 4 cm

Corresponding height = h = 3 cm

Area = ( a + b ) h /2

= [ ( 6 + 4 ) 3 ] /2

= ( 10 × 3 ) / 2

= 30 /2

= 15 square cm

I hope this helps you.

:)

15 cm hope it helps thank you

the 3rd on is correct

step-by-step explanation:

5x + 3y = - 4

step-by-step explanation:

the equation of a line in standard form is

ax + by = c ( a is a positive integer and b, c are integers )

express the line first of all in slope- intercept form

y = mx + c ( m is the slope and c the y-intercept )

to calculate m use the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (7, - 3) and (x₂, y₂ ) = (4, - 8)

m = = -

y = - x + c ← is the partial equation

to find c substitute either of the 2 points into the partial equation

using (4, - 8 ), then

- 8 = - + c ⇒ c = -

y = - x - ← in slope-intercept form

multiply all terms by 3 to eliminate the fractions

3y = - 5x - 4 ( add 5x to both sides )

5x + 3y = - 4 ← in standard form
