How do you solve the equation 5/x= x-4

Answers

Answer 1

Answer:

Answer:

x=5

Step-by-step explanation:

write x - 4 as a fraction with denominator = 1

5/x = (x - 4)/1

Now cross multiply

x(x - 4) = 5 multiply out and collect all terms on the left side of the equal sign

x2 - 4x - 5 = 0 factor the quadratic into two binomials

(x - 5)(x + 1) = 0 the product of two numbers = 0 when either number is zero

Therefore x = 5 or x = -1

How do I solve 17(x+5)=0

Please help!!!A triangle has one side that measures 9 units, another side that measures x, and a third side that measures 2 units more than x. The perimeter is 29 units.

Which equation would we use to find the value of x?

x + x + 2 = 29
x + x + x + 2 + 9 = 29
x + x + 2 + 9 = 29
x + x + x + 2 = 29

Answers

The right answer is: x + x + 2 + 9 = 29

Step-by-step explanation:

According to given statement,

Side 1: 9 units

Side 2: x units

Side 3: x+2 units

The perimeter of a triangle is given by

$Side1+Side2+Side3=P\n$

Putting the values we get

$(9) + (x) + (x+2) = 29\n9+x+x+2=29\nx+x+2+9=29$

Hence,

The right answer is: x + x + 2 + 9 = 29

You set up the equation by adding all sides together. Then set the equation equal to 102 since that is the total perimeter. To solve for the variable, (a) you first want to combine like terms. (That is where the picture starts)

Answer:

The longest side length is 31.764705882352941

Step-by-step explanation:

Add up all the sides and then make it equal to 102

To get perimeter you add up all the sides

(12a) + (6a + 8) + (6a + 8) + (10a - 4) = 102

(18a +8) + (16a + 4) = 102

34a + 12 = 102

- 12 - 12

34a = 90

$(34a)/(34) = (90)/(34)$
