Answer:
x ≈ - 1.83
Step-by-step explanation:
to solve for x in the question 1.1x + 1.2x - 5.4 = -10
we have
2.3x - 5.4 = -10
collect the like terms
2.3x = -10 + 5.4
2.3x = -4.2
divide both sides by the coefficient of x
2.3x/2.3 = -4.2/2.3
x = -1.826
x ≈ - 1.83
Circumference = 2πr
6.28 = 2πr
12 = 2n/3 +7n/3 -6
6.28 = 2×3.14×r
r =6.28/2×3.14
r= 1 unit
Now,
Area of a circle = πr² = 3.14×1×1= 3.14 sq.units

Answer:
6.5x^2 + 5.5x + 1
Step-by-step explanation:
6.5 x * x + 5 .5 x + 1 can be re-written as 6.5x^2 + 5.5x + 1, or as:
65x^2 + 55 + 10
