Step-by-step explanation:

4x+3y=21

4x+2y=16

If we add both the equation:

4x + 3y = 21

4x + 2y = 16

(-) (-) (-)

4x + 3y = 21

-4x - 2y= -16

=> 0+1y= 5

y=5

substituting Y in eq 1

4x+3y=21

4x+3(5)=21

4x+15=21

4x=21-15

4x=6

x=1.5

<h3 /><h3>x=1.5 and y=5</h3>

Tamiku [17]
Actual area of the rectangular building = 5040 feet²
Step-by-step explanation:
Length of the rectangular building = 7 feet
Width of the rectangular building = 5 feet
Now, The building is made with a scale factor of 12
So, Actual length of the rectangular building = 84 feet
Actual width of the rectangular building = 60 feet
Now, Actual area of the rectangular building = Length × Width
⇒ Actual area of the rectangular building = 84 × 60

The point A has co-ordinates (-4,6) and the point B has co-ordinates (7,-2).
Serhud [2]

Answer:

√185 or 13.60 units to the nearest hundredth.

Step-by-step explanation:

For the points (x1,y1) and (x2,y2) the length between the points is given by:

L = √ [ (x2-x1)^2 + (y2-y1)^]

So here we have:

Length of AB  √ [ (7- - 4)^2 + (-2 - 6)^2]

=  √ (121 + 64)

= √185.
