Answer:

Constructed figure is a rectangle.

Step-by-step explanation:

According to question we have ∠N=∠M=∠O=90°

And MN = 5 cm  and NO = 7 cm

That means adjacent sides are not equal.

The sum all the angles of a quadrilateral is equal to 360°.

∴∠P=90°

A quadrilateral is said to rectangle if all angles measures 90° and their adjacent sides are not same.

Brilliant_brown [7]

Answer:

x = -13

Step-by-step explanation:

or, (4x-7)/x = (5x+6)/x

or, (4x-7) = (5x +6)

[the x gets cancelled when it comes to opposite side]

or, 4x-5x = 6+7

or, -x = 13

or, x = -13

what is the solution to the system of equations: x- - y-z = 2, - x - 3 y - 2 z + 4, -x - 2 z = 10
ladessa [460]

Given equations are x- - y-z = 2, - x - 3 y - 2 z + 4, -x - 2 z = 10 .

It seems you have missed to write = in the 2nd equation so i have fixed the sign and going to solve the following system of equations:

x-y-z=2 ...(i)

-x-3y-2z=4 ...(ii)

-x-2z=10 ...(iii)


solve (i) for x

x=2+y+z ...(iv)

plug (iv) into (ii)

-x-3y-2z=4

-(2+y+z)-3y-2z=4

-2-y-z-3y-2z=4

-2-4y-3z=4

-4y-3z=6...(v)


plug (iv) into (iii)

-x-2z=10

-(2+y+z)-2z=10

-2-y-z-2z=10

-2-y-3z=10

-y=12+3z

y=-12-3z...(vi)


plug (vi) into (v)

-4y-3z=6

-4(-12-3z)-3z=6

48+12z-3z=6

48+9z=6

9z=-42

z=-14/3


Now plug value of z into (vi)

y=-12-3z=-12-3(-14/3)=-12+14=2

y=2


plug value of y and z into (iv)

x=2+y+z=2+2-14/3=-2/3


Hence final answer is x=-2/3, y=2, z=-14/3
