A square has 4 sides which are ALL equal.
so we would just do square root 20
=4.472
so I think a tenth would just be 4.5 ( rounded to 1d.p. )
hope this helped :)

The length of one side is 4.5. To find the area of a square, you multiply a side by a side. if you multiply 4.5 with 4.5, it equals 20.25.

Step-by-step explanation:

The area A of the tire in contact is 7"×5" = 35 sq inches and we know that each tire has a pressure of 30 psi so the weight of the car in tons is

$W = \dfrac{APN}{2000} = \dfrac{(35\:\text{in}^2)(30\:\text{lbs/in}^2)(4)}{2000}$

$\:\:\:\:\:= 2.1\:\text{tons}$

Step-by-step explanation:

2(0.4)^-2

=2(6.25)

= 12.5

2(0.4)^-1

= 2(2.5)

2(0.4)^0

=2(1)

2(0.4)^1

=2(0.4)

=0.8

2(0.4)^2

What are the roots of -12x^2+11×-3=0

Anastasy [175]

Consider, pls, this solution:

If given a equation:
-12x²+11x-3=0, then
12x²-11x+3=0
D=b²-4ac=121-12*12=-23<0
$\left[\begin{array}{ccc} x= \frac{11-i \sqrt{23}}{24} \\ \ x= \frac{11+i \sqrt{23}}{24} \end{array}\right$
