Answer:
4.5 u
Step-by-step explanation:
There are many ways to do it, the most easier is this:
Area=(b*h)/2
Area of ABD = (3*3)/2 = 4.5 u
The formula for this is: (sale price) / (1 - percentage)
Percentage have to be in decimal form, so divide percentage by 100 to get the decimal form.
220/(1-.20) = $275
The original price was $275.
Y=mx+b is slope intercept form...
m=slope
b=y-intercept
Answer- y=-9+5
- 4x^2y * 3xy^3
multiply the numbers : 4*3 = 12
-12x^2xy^3y
apply exponent rule : x^2x = x^2+1 = x^3
-12x^3y^3y
apply exponent rule again : y^3y = y^1+3 = y^4
answer : -12x^3y^4
