Answer:
60 cm²
Step-by-step explanation:
base = 10
Height = √13² - 5² = √144 = 12
area = 1/2BH = 1/2 * 10 * 12 = 60
Step-by-step explanation:
3 x^3-15x^2+18x 3(x^3-5x^2+6x)
Answer:
we know that,
y-y1=m(x-x1)
or, y-1=-3(x-5)
or, y-1=15-3x
or 3x+y-16=0 is the required equation
32*1.2=38.4 (.2 is the 20%, and the 1 adds the percent to the original cost making it a mark up)
