Find value of X in the isosceles triangle shown below

Mathematics
1 answer:
EleoNora [17]3 years ago
3 0

Answer:

A

Step-by-step explanation:

You have to use Pythagorean theorem.

a^2 + b^2 = c^2

x^2 + 3^2 = 5^2 (you know that b=3 because is the half of 6)

x^2 + 9 = 25

x^2 = 25 - 9

x^2 = 16

x = √16

x = 4

Will an object 20ft below sea level have a different absolute value than an object 20ft above sea level .. explain
trapecia [35]

No, the objects below the sea and above both have the absolute value of 20 ft.

The absolute value is how far the number is away from zero- it doesn't matter if it is in the positive or negative direction

For example, if you drove 20 miles from your house in one direction while your friends drove 20 miles in the other direction- both of  the distances of you and your friend from the your house is 20 miles.

Distance is a great example of the absolute value because it is always positive. It doesn't matter what direction, it is always 20 miles from your house.

Angelina_Jolie [31]

Answer:

please pretty please mark brainlist

Step-by-step explanation:

number of plants = 647

number of plants in 1 rows = 20

number of rows =

647 ÷ 20 = 32 and remainder = 7 =>

647 = 32 × 20 + 7 =>

647/20 =

(32 × 20 + 7) / 20 =

32 + 7/20 =

32 7/20

The Quadratic Equation c² + 6c+ 8 = 0<br><br> Show work please
Bad White [126]
The formula for the quadratic formula is x (c in this case) = (-b(+/-)√(b²-4ac))/2a
This is used for an equation in standard quadratic form: ax² + bx + c = 0
1.) Put it in the correct form, if not already in it.
Ex. c² + 6c + 8 = 0
2.) Identify each part of the equation:
a = 1 (the leading coefficient), b = 6 (the coefficient in front of the second variable), c = 8
3.) Plug in each variable answer
c = (-6(+/-)√(6²-4(1)(8))/2(1)
4.) Simplify
c = (-6(+/-)√(36-(4*8))/2
c = (-6(+/-)√(36-32))/2
c = (-6(+/-)√(4))/2
c = (-6(+/-)2)/2
*Here, the equation splits in two. It becomes:
c = (-6+2)/2 AND c = (-6-2)/2
*Simplify again:
c = -4/2 AND c = -8/2
c = -2 AND c = -4
The answers c = -2 and c = -4 would solve the given equation.
Hope this helps! :)
