Answer:
824.05
Step-by-step explanation:
the hundreths place is two spots behind the decimal, there is a four. Look at the number next to it is a 7 so you round up
Answer:
i meant 7 bc it is isosceles.
Step-by-step explanation:
♥ Answer: x=-6.9
Solve:
You need to <span>Simplify both sides of the equation.
</span>

Now: <span>Flip the equation.
</span>

<span>
</span>Lastly <span>Divide both sides by -116.85.
</span>
Final answer: x=-6.9
Answer: the perimeter of the shape is 19.1
Step-by-step explanation:
To determine the length of each side of the quadrilateral, we would apply Pythagoras theorem which is expressed as
Hypotenuse² = opposite side² + adjacent side
For line AD,
AD² = 2² + 4² = 4 + 16 = 20
AD = √20 = 4.47
For line AB,
AB² = 1² + 5² = 1 + 25 = 26
AB = √26 = 5.1
For line BC,
BC² = 2² + 4² = 4 + 16 = 20
BC = √20 = 4.47
For line CD,
CD² = 1² + 5² = 1 + 25 = 26
CD = √26 = 5.1
The perimeter of a plane figure is the distance around the figure. Therefore
Perimeter = AB + AB + BC + CD
Perimeter = 4.47 + 5.1 + 4.47 + 5.1 =
19.1
