Answer:
√2x.
Step-by-step explanation:
√x * √2 = √(2x).
Its the second option.
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:
2/3 = 3/2
Step-by-step explanation:
A) The two angles are supplementary and form a linear pair. This means that their combined measure is 180 degrees.
B) 2x + 68 = 180
C) subtract 68 from both sides. 2x = 112. Divide both sides by 2. x = 56.
If we plug 56 back into the equation 2x, we get 112. The if we add 112+68 we get 180, which means that the two are a linear pair.
Answer:
c. 74
Step-by-step explanation:
We know that the two lines are parallel, therefore Angle N and Angle F are equivalent as they are corresponding angles. We can first find Angle F to find Angle N.
Angle F + 106 = 180 (Linear pair/supplementary angles)
Angle F = 74
Angle N = Angle F
Angle N = 74
