All I know is that question 1 is B and I think for question 3 is Sammy is correct.
Answer:
11
Step-by-step explanation:
The Answer:
21 - 9 = 12, not 11.
explanation:
It is not much else to say here, so straightforward, the answer lies above.
Therefore,
you are correct. 11 + 9 = 20 - 9 = 11, which is correct for the given equation.
Answer: AE = 120.83 m DE= 148.66 m
The perimeter of the pentagon is 699.49
Sketch attached.
Step-by-step explanation: First we have to imagine the shape of the pentagon. In order to satisfy the requirement "that E is 50 m from the side AB and 30 m from the side BC," <em><u>this must be a concave pentagon. </u></em>
To determine the lengths of sides AE and DE, subtract the given distances of E from the lines, and use those values in the Pythagorean Theorem.
AE:

DE:

Add those lengths and the remaining sides of the "rectangle shown below" to calculate the perimeter.
280+150+120.83+148.66= 699.49
you have to reduce this expression before
4.8+w(2.-1.4)+2.4
4.8+2.4+0.6w
7.2+0.6w
