First add plus 5 to -5 and 22. Then -5 cancels outdo now u have 3b=27. Divide 3 to 3b and 27. Then you will have b=9
Answer:
1.
-3|2x+6|=-12
|2x+6|=4
2x+6=4
2x+6=-4
x1=-5, x2=-1
2.
|x-2|+10=12
|x-2|=12-10
|x-2|=2
x-2=2
x-2=-2
x1=0, x2=4
If a triangle is made up of side lengths a, b and c
Given that c is the longest side length of the triangle,
The Pythagorean theorem can be used to tell if the triangle
is obtuse, acute or right
In an obtuse triangle,
a^2 + b^2 < c^2
In an acute triangle,
a^2 + b^2 > c^2
In a right angled triangle,
a^2 + b^2 = c^2
Answer:
A. 3x3x3x3 = 81 because you multiply 3 by itself 4 times
