Marcus is 1.5 meter tall his sister is 0.1 meter taller than marcus their father is 0.2 meter taller than his sister how tall is the father

The father is 1.8 meters tall.  To find this we know that Marcus is 1.5 meters tall and that his sister is 0.1 meter taller (1.6 meters) and if the father is 0.2 meters taller than the sister who is 1.6 meters tall that means the father is 1.8 meters tall.

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
