Answer:
Step-by-step explanation:
First we need to make sure that the leading coefficient is a 1. Ours is a 4, so we need to factor it out, leaving us with
To complete the square, take half the linear term, square it, then add it to both sides. But don't forget about that 4 hanging around out front, refusing to be ignored. Our linear term is 18. Half of 18 is 9, and 9 squared is 81. Add 81 into the parenthesis, but what we REALLY added in was 4*81 which is 324:
To solve this, we need to get the x terms all by themselves. So let's divide both sides by 4 to get
The process of completing the square created a perfect square binomial on the left. We will state this binomial now:
We isolate the x term by taking the square root of both sides:
x - 9 = ±9
From that we have 2 equations:
x - 9 = 9 and x - 9 = -9
Which means that x = 18 or x = 0
Answer:
114ft
Step-by-step explanation:
3 times 3=9
9times 2=18
8 times 3=24
24 times 2=48
8 times 3 = 24
24 times 2 =48
48+48+18=114
The answer is x=1.3
You are welcome
X = 66°
The area folded over is a right triangle, and its void is a right triangle as well. We have one angle marked 33° and a right angle in the bottom left. This leaves us 180-(33+90) = 180-123 = 57°.
The folded over triangle has the same angle measurements.
We have two angles to the left of x, which form a straight angle with x. Straight angles have a sum of 180°. The angles that form the straight angle with x both have a measure of 57°. This gives us:
180-(57+57) = 180-114 = 66°
