Every multiples of 10s has a zero... you do know that... right?
Area = side AB * side BC = (5x + 5x + 3)(3x + 92x - 4)
= (10x + 3)(95x - 4) = 950x^2 - 40x + 285x - 12
= 950x^2 + 245x - 12 Answer
This cannot be negative so restriction on x is 950x^2 + 245x > 12
That is x > 0.0421
The total amount of paint needed is 15 quart and it cost $41.25.
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more variables and numbers.
0.0015 quart of paint to cover 1 square inch.
Let the area of the rectangle be 10000 in², hence:
Amount of paint = 0.0015 quart per in² * 1000 in² = 15 quart
Cost of paint = $2.75 per quart * 15 quart = $41.25
The total amount of paint needed is 15 quart and it cost $41.25.

Answer:
x=30. y=60
Step-by-step explanation:
DG is a straight segment so it sums to 180 degrees. ECG is a right angle so 90 degrees. The rest is described as 2x and x. So 3x=90 degrees. x=30. Eh is also a straight segment. since we know x, we know that ECD is 60 degrees. So y+y=120 degrees. 2y=120. y=60.
