Rectangle ABCD has vertices at (-7,-2); (1, -2); (1, -8); and (-7, -8) respectively. If GHJK is a similar rectangle where G(2, 5
Gennadij [26K]

Answer:

Points J and K could be located at:

J(2,2)

K(6,2)

Step-by-step explanation:

Consider the vertices have a x and y coordinate:

A: x coordinate=-7  y coordinate=-2

B: x coordinate=1  y coordinate=-2

C: x coordinate=1  y coordinate=-8

D: x coordinate=-7  y coordinate=-8

G: x coordinate=2  y coordinate=5

H: x coordinate=6  y coordinate=5

Then it is possible to calculate the distance between the x and y coordinates:

x coordinate of Vertices AB:

x coordinate of B- x coordinate of A=1-(-7)=8

The distance between A and B is 8

y coordinate of Vertices AC:

y coordinate of A- y coordinate of C=-2-(-8)=6

The distance between A and C is 6

Then we know that the side AB of Rectangle ABCD measures 8 and the side AC, measures 6.

Repeat the analysis  with Rectangle GHJK. In this case, is only possible to calculate the distance with x coordinate.

x coordinate of Vertices GH:

x coordinate of H- x coordinate of G=6-(2)=4

The distance between G and H is 4

We can see that the distance in x of the Rectangle ABCD is 8, and the distance in x of the Rectangle GHJK is 4, it means that <em>the measure of ABCD is twice GHJK.</em>

Then, if the distance in y coordinate of Vertices AC is 6, we could say that the distance in<em> y coordinate of Vertices GJ is 3.</em>

Points J and K could be located at:

J(2,2)

K(6,2)

Why is 1/8 greater than 1/10 but less than 1/3

Is p = -1 a solution to the equation 6(p – 4) = -30p?
jenyasd209 [6]
To know if p = -1 is a possible solution to <span>6(p – 4) = -30p, plug in -1 for p and see if the equation is true.

</span><span>6(p – 4) = -30p
</span><span>6(-1 – 4) = -30(-1)

</span>6(-1 – 4) = -30(-1)<span>
Solve the parentheses.
-1 - 4 = -5

</span>6(-5) = -30(-1)
Multiply.
6 • -5 = -30
-30 • -1 = 30

-30 = 30
This is not true, so p = -1 is NOT a possible solution for the <span>equation 6(p – 4) = -30p.

Hope this helps!</span>

leonid [27]

Answer:

-47

Step-by-step explanation:

-x + 9 = 56\\-x = 56-9\\-x = 47\\x = -47 \\\\Verification:\\LHS= - x+9 = -(-47) +9 = 47+9 = 56 = RHS

Hassan built a fence around a square yard. It took 48 m^2 of lumber to build the fence. The fence is 1.5 meters tall.
Gennadij [26K]

Answer:

Step-by-step explanation:

<u>Please check ones more because this might be incorrect.</u>

The area is in square meters...Let's change it

Square 48= 48*48 =2304

2304 divided by 4( 4 since the formula for the area of a sqaure is s*s and square has 4 sides)

2304 divided by 4 = 576

The formula for area of a square is S*S(side times side)

Let's apply the formula here.

so, 576 times 576

331776 square meters

Hope this is right and helps! :)

<u>( This just my point of view. Please check this onces again)</u>
