Add the mixed number fractions. Simplify, if possible.
Vladimir79 [104]

Answer:

8 4/15

Step-by-step explanation:

Rewriting our equation with parts separated

= 5 + 2/3 + 2 + 3/5

Solving the whole number parts

5 + 2 = 7

Solving the fraction parts

2/3 + 3/5 = ?

Find the LCD of 2/3 and 3/5 and rewrite to solve with the equivalent fractions.

LCD = 15

10/15 + 9/15 = 19/15

Simplifying the fraction part, 19/15,

19/15 = 1 4/15

Combining the whole and fraction parts

7 + 1 + 4/15 = 8 4/15

The sides of a triangle are x , x +1 , 2 x -1 and its area is x root of 10 .Find the value of x.
VARVARA [1.3K]


Ok, I'm going to start off saying there is probably an easier way of doing this that's right in front of my face, but I can't see it so I'm going to use Heron's formula, which is A=√[s(s-a)(s-b)(s-c)] where A is the area, s is the semiperimeter (half of the perimeter), and a, b, and c are the side lengths.

Substitute the known values into the formula:

x√10=√{[(x+x+1+2x-1)/2][({x+x+1+2x-1}/2)-x][({x+x+1+2x-1}/2)-(x+1)][({x+x+1+2x-1}/2)-(2x-1)]}

Simplify:

<span>x√10=√{[4x/2][(4x/2)-x][(4x/2)-(x+1)][(4x/2)-(2x-1)]}</span>

<span>x√10=√[2x(2x-x)(2x-x-1)(2x-2x+1)]</span>

<span>x√10=√[2x(x)(x-1)(1)]</span>

<span>x√10=√[2x²(x-1)]</span>

<span>x√10=√(2x³-2x²)</span>

<span>10x²=2x³-2x²</span>

<span>2x³-12x²=0</span>

<span>2x²(x-6)=0</span>

<span>2x²=0 or x-6=0</span>

<span>x=0 or x=6</span>

<span>Therefore, x=6 (you can't have a length of 0).</span>
