The value of x is 1.14 or x = -1.47

We find the value of x in the quadratic equation 3x^2 +x-5=0

Using the formula: (-b ± √ (b²- 4 a c)) / (2a)

Where the value of a = 3, b = 1 and c = -5

Substituting the above values (a = 3, b = 1 and c = -5)

in the formula:

(-1 ± √ (1²- 4 3 (-5))) / (2*3)

= (-1 ± √ (1+60)) / (6)

= (-1 ± √ (61)) / (6)

= (-1 ± 7.81) / (6)

= (-1 + 7.81) / (6) or (-1 -7.81) / (6)

= (6.81) / (6) or (-8.81) / (6)

=1.135 or -1.468

Hence the value of x= 1.14 or -1.47

If you draw a net for a cylinder, such as a soup can, how many two-dimensional geometric shapes would this net have?
Nezavi [6.7K]

Answer:

3.

If you were to “unroll” a can of soup, you would end up with two circles and one rectangle.

Thats why when you are finding the surface area of a cylinder, you need to multiply the area of the circle by 2. And also you need to find the area of the rectangle. Then you add the areas all up.

please mark me brainlies :)

Which of the I-values are solutions to both of the following inequalities?
lidiya [134]

Answer:

Option (C)

Step-by-step explanation:

Given inequalities are,

81 > x and x > 68

Therefore, 81 > x > 68 is the inequality representing the solution area for x.

Out of x = 88, 85 and 80,

x = 80 will lie between the range of x = 68 and x = 81.

Therefore, Option (C) will be the correct option.
