What is the value of x in the equation –x = 4 – 3x + 6?

Nataly [62]

Remember you can do anything to an equaiton as long as you do it to both sides

-x=4-3x
add 3x both sides
3x-x=4+3x-3x
2x=4+0
2x=4
divide 2
2x/2=4/2
2/2x=2
1x=2
x=2

An obtuse triangle is formed if there is an angle that has a measure of more than 90 degrees. You can determine if an obtuse angle is formed by two sides of a triangle if it meet this condition:

Let a and b be two sides of a triangle and c is the longest side:
$a^{2} + b^{2} \ \textless \ c^{2}$

So taking your given:

$10^{2} + 15 ^{2}$ < $c^{2}$
100 + 225 < $c^{2}$
325 < $c^{2}$

To get the smallest possible number, just get the square root of both sides:

$\sqrt{325}$ < $\sqrt{c^{2} }$
18.03 < c

So your smallest possible whole number is 19

Can someone help me understand these questions?

kite is a quadrilateral whose four sides can be grouped into two pairs of equal-length sides that are adjacent to each other.

a square does fir this definition since it has 4 equal sides, hence 2 pairs and hte equal sides are adjacent to each other.
so yes a square is a kite

the definition of a rectangle is 
a figure with four straight sides and four right angles, 

a parallelogram with 4 right angle woudl be a rectangle but any without would not

so it can be, but generally is not

Gnesinka [82]

Answer:

Step-by-step explanation:

Suppose we a point $P(x,y,z)$ such that its distance from either the point $A(3,4,-5)$ or $B(-2,1,4)$ is the same.
