What is the area of the real object that the scale drawing models? scale factor 1:5
area of scale drawing: 12 square cm
area of real object: ?​

60

Step-by-step explanation:

1×5=5

12×5=50

60

It's 60 square cm

Step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
