All you do is change signs write 2x minus 14 equals negative 10-14 equals four then you write 2x over two equals four over two then u write x equals negative two
Answer:
x = 3.5; perimeter = 59; area = 8
Step-by-step explanation:
isosceles means the two legs equal each other so use same expression later on
6x + 8 = 2x - 6
6x - 2x = -8 - 6
4x = -14
x = 3.5
plug x value in the first expression to find the two sides that are equivalent to each other
6(3.5) + 8
21 + 8
29
plug x value into the second expression (the base)
2(3.5) - 6
7 - 6
1
perimeter = side 1 + side 2 + side 3
perimeter = 29 + 29 + 1
perimeter = 59
area = base × height/2 or bh/2
first plug in x value into height expression
4x + 2
4(3.5) + 2
14 + 2
16
area = 1 × 16/2
area = 16/2
area = 8
Answer:
all real numbers
Step-by-step explanation:
3x-8 = -x + 4(x-2)
distributive property:
3x - 8 = -x + 4x-8
Combine like terms:
(add 3x to both sides)
-8 = -8
That means that x can be any number, because in the end, x will be canceled out from the equation.
