What is ( √2 - √3 )² =
allochka39001 [22]

just use FOIL (First, Outer, Inner, Last).

( √2 - √3 ) X ( √2 - √3 )

First: √2 X √2 = 2
Outer: √2 X -√3 = -√6
Inner: -√3 X √2 = -√6
Last: -√3 X -√3 = 3

and then add them together.

2 - √6 - √6 + 3
5 - 2(√6)

The answer is 5 - 2(√6) .

Solve: 3(2x - 5) = 6x - 15
Levart [38]
3(2x-5)=6x-15

3(2x-5) :

6x-15 = 6x-15

add 15 to both sides:

6x-15+15=6x-15+15

6x =6x

subtract 6x from  both sides:

6x-6x=6x-6x

0=0

Both sides are equal : true  for all x

Answer D

hope this helps!

if 3/4 of one of the acute angles of a right angled tringle is 15-1/4" larger than1/6 of the other,find the acute angels
Vaselesa [24]

The acute angles in the triangle are 16.6 degrees and 73.4 degrees

<h3>How to determine the acute angles?</h3>

From the question, we have:

Triangle type = Right triangle

Let the acute angles be x and y.

So, we have:

3/4x = 1/4 + 1/6y

Multiply through by 12

9x = 3+ 2y

The sum of acute angles in a right triangle is

x + y = 90

Rewrite as

y = 90 - x

Substitute y = 90 - x in 9x = 3+ 2y

9x = 3+ 2(90 - x)

Open the brackets

9x = 3+ 180 - 2x

Evaluate the like terms

11x = 183

Divide by 11

x = 183/11 = 16.6

Substitute x = 183/11 in y = 90 - x

y = 90 - 183/11

Evaluate

y = 807/11 = 73.4

Hence, the acute angles in the triangle are 16.6 degrees and 73.4 degrees
