Mathematics

tresset_1 [31]3 years ago
3 0

Answer:

x = 29

y = 13

Step-by-step explanation:

Write 2 equations:

x + y = 42

x - y = 16

Isolate x in the first equation:

x = 42 - y

Substitute this in for x in the second equation:

42 - y - y = 16

42 - 2y = 16

solve for y:

-2y = -26

y = 13

Plug in 13 for y in either equation:

x + 13 = 42

Solve for x:

x = 29

Perimeter=2x+2y\\\\
175=2x+2y\\
x=2y+6\\\\
175=2(2y+6)+2y\\
175=4y+12+2y\\
175=6y+12\ \ \ |Subtract\ 12\\
163=6y\ \ \ |Divide\ by\ 6\\
y=27,17feet\\\\
x=2*27,17+6=60,34feet\\\\

<h2>Answer:</h2>

Luke does a work of 308Nm

<h2>Step-by-step explanation:</h2>

If we have a constant force \vec{F} that acts on a body in the same direction as the displacement \vec{s}, then the work W is defined as the product of the force magnitude F and the displacement magnitude s. In other words:

W=Fs, which is valid for a constant force in direction of straight-line displacement.

In this problem:

F=22N \\ \\ s=14m

Therefore:

W=22\times 14 \\ \\ \boxed{W=308Nm}
