X to the 2 power 2x-15=0

Mathematics

lilavasa [31]4 years ago

To solve x^2+2x-15=0, First we will factor the trinomial. So, when it is factored, it will look like this: (x+5)(x-3). We will set both equal to 0. x+5=0 and x-3=0. Solve for x in each equation. x= -5 or 3

Using the figure, find x and y
kakasveta [241]

Answer:

  • x = 8
  • y = 2√3

Step-by-step explanation:

The triangle is recognizable as a 30°-60°-90° right triangle, which has side length ratios ...

  1 : √3 : 2

Side x is thus twice the length of short side 4, so x = 8.

Side y is √3 times the length of short side x-6 = 2, so y = 2√3.

_____

If you don't happen to recognize the triangle dimensions, you can find x and y using the Pythagorean theorem.

  x = √(4² +(4√3)²) = √64 = 8

  y = √(4² -2²) = √12 = 2√3

How do you factorise xy zy?
alexandr1967 [171]
Assuming you meant to write: "xy + zy"
The answer is: xy + zy = y(x + z)
The one variable that appear multiple times is: "y". There are no coefficients (other than the implied coefficients of "1"; since "1" multiplied by any number equals that very number).  Since "y" appears twice, we can "factor out" a "y" ; as follows: 
________________
y(x+z).
____________________
Take note of the distributive property of multiplication:
_____________________
a(b+c) = ab + ac ;
_________________
AND: a(b-c) = ab - ac.
____________________
Likewise: y(x+z) = yx +yz 
                        = xy zy

A baby who was 18 inches at birth is now 24 inches by what percentage did the babys height increase
Kazeer [188]

Answer:

≈33.3%

Step-by-step explanation:

First we find the difference of the heights to see what the growth was

24-18 = 6

Then we find what percent 6 is of 18 to see what percentage growth occured

6/18 ≈33.3%
