evaluate each expression using properties of numbers. Name the property used in each step. 1. 6.4+2.7+1.6+53 2. 4/3×7×3×10

false

step-by-step explanation:

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

a)(x-2)^2+(y-1)^2=9
