Madeline is standing 2x−4 feet from the base of a tree. The height of the tree is 5x+6 feet. Find the equation that shows the st

klemol [59]

Answer:

Required equation is $\sqrt{(2x-4)^2+(5x+6)^2}$ .

Step-by-step explanation:

Given,

Height of the tree=5x+6

Distance from feet of the tree=2x-4

To find straight distance from feet of Madeline to top of the tree.

Let the tree as y-axis and distance from base along x-axis. Then the distence of straight line from foot of Madeline to top is become the hypotenuse of the triangle. Thus if we let,

Distance from feet of Madeline to top of tree= p, then, according to law of finding third side of a triangle we get,

$p^2=(\textit{distance from base})^2+(\textit{height of tree})^2$

$\therefore p=\sqrt{(2x-4)^2+(5x+6)^2}$

Hence the result.

Find x when y=3 in the literal equation 3x+6y=24

pshichka [43]

When you plug in 3 in for y the equation is 3x + 6(3) = 24

3x + 18 = 24

subtract 18 from both sides

3x = 6

Isolate the x by dividing both side by 3

x = 2
