Hello :
x²- 2x+10 = 0
(x²-2x+1) -1 +10
(x-1)² +9 = 0
(x-1)² = -9 ... .(no real solution because : (x-1)² <span>≥ 0 )</span>

vovangra [49]

Answer:

The large number is 17

Step-by-step explanation:

x+y=31⟹x=31−y

2x=y+11⟹x=y+11/2

2(y+11/2)=2(31−y)

y+11=62−2y

3y=51

y=17 x=14

Hope this helps, have a nice day! :)

Is the circumference of all circles about 3 times greater than their diameters. and why?

stira [4]

Answer:

<h2>Yes the circumference is about times greater than their diameters</h2>

Step-by-step explanation:

We will approach this problem by doing a check

Say the diameter of a circle is 4 cm

Hence the radius is 3 cm

We know that the circumference is $C=2\pi r$

$C=2*3.142*2= 12.57cm$

The circumference is about 3 time bigger than the diameter

Let us try another case say the diameter is 6 cm

The radius is 3 cm

$C=2*3.142*3= 18.85cm$
