Answer:

Step-by-step explanation:
The picture of the question in the attached figure
we know that
The triangle ABD is an isosceles triangle
because
AB=BD
The segment BM is a perpendicular bisector segment AD
so
<em>In the right triangle ABM</em>
Applying the Pythagorean Theorem

we have

substitute

-----> equation A
<em>In the right triangle BMC</em>
Applying the Pythagorean Theorem

we have

substitute


----> equation B
equate equation A and equation B

solve for x

Simplify

<em>Find the length of DC</em>

substitute the given values


Mary has a collection of nickels and quarters for a total value of 4.90.if she has 42 coins total how many of each kind are there
When x = -4,
g(-4) = |-3*(-4) - 1| = 11
So, 2g(-4) = 2 * 11 = 22
[Where * represents multiplication.]
