Step-by-step explanation:

2 1/10 + 3/100 = 200/100 + 10/100 + 3/100 = 213/100 =

= 2 13/100

2 1/10 + 5 3/100 = 200/100 + 10/100 + 500/100 + 3/100 =

= 713/100 = 7 13/100

2.1 + 00.3 = 2.4

or did you mean + 100.3 ? then is is 102.4

24/100 + 7/10 = 24/100 + 70/100 = 94/100 = 47/50

3 24/100 + 8 7/10 =

= 300/100 + 24/100 + 800/100 + 70/100 =

= 1194/100 = 11 94/100 = 11 47/50

What is the factored form of the expression?<br><br> d^2 = 36d + 324

Veseljchak [2.6K]

Answer:

$(x-43.45)(x+7.45)=0$

Step-by-step explanation:

We have the quadratic equation $d^{2}=36d+324$ i.e. $d^{2}-36d-324=0$

As, the roots of the quadratic equation $ax^{2}+bx+c=0$ are given by $x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}$ .

So, from the given equation, we have,

a = 1, b = -36 , c = -324.

Substituting the values in $x=\frac{-b\pm \sqrt{b^{2}-4ac}}{2a}$ , we get,

$x=\frac{36\pm \sqrt{(-36)^{2}-4\times 1\times (-324)}}{2\times 1}$

i.e. $x=\frac{36\pm \sqrt{1296+1296}}{2}$

i.e. $x=\frac{36\pm \sqrt{2592}}{2}$

i.e. $x=\frac{36\pm 50.9}{2}$

i.e. $x=\frac{36+50.9}{2}$ and $x=\frac{36-50.9}{2}$

i.e. $x=\frac{86.9}{2}$ and $x=\frac{-14.9}{2}$

i.e. x = 43.45 and x = -7.45

Thus, the roots of the equation are 43.45 and -7.45.

Hence, the factored form of the given expression will be $(x-43.45)(x+7.45)=0$
