The formula for area of triangle is -

________________________________
So, the area of first triangle =



________________________________
Area of second triangle =



________________________________
Area of second triangle - Area of first triangle



54 can be factored as follows:
54
2*27
2*3*9
2*3^2*3
2*3^3
Therefore, 54 is equal to 2*3^3, or 2*3*3*3.

Answer:
-2/3
Step-by-step explanation:
The gradient of a line is its slope. You can just convert the equation to slope-intercept form (y=mx+b where "m" is the gradient/slope):
3y + 2x = 1
3y = 1 - 2x
y = 1/3 - 2/3x
y = -2/3x + 1/3
So, as we can see, -2/3 is the gradient/slope of the line.

Answer:
(A) -2, 3/7, 1/2, 1.2
Step-by-step explanation:
The numbers are in increasing order when they are listed left-to-right as they appear on the number line.
The only numbers that may give you trouble are 3/7 = 6/14 and 1/2 = 7/14.
The negative number is less than any positive number. 1.2 is greater than any fraction that is less than 1.
The correct ordering is found in choice A.
