For this case the area is given by:
A = (22 + x) * (28 + x) = 722
Rewriting we have:
616 + 22x + 28x + x ^ 2 = 722
x ^ 2 + 50x + 616 - 722 = 0
x ^ 2 + 50x - 106 = 0
Solving the polynomial we have:
x1 = 2.04
x2 = -52.04
We take the positive root:
x = 2.04 inches:
Answer:
The width of the border to the nearest inch is:
x = 2inches
Answer:
Shown Below
Step-by-step explanation:
Alright so first off we are going to use the little 67 on that corner. We know that it's a supplementary angle, and supplementary angles add up to 180.
180 - 67 = 113.
Inside angles of a triangle all add up to 180. Using that we can create the equation:
(x + 27) + x + 113 = 180
simplify.
2x + 140 = 180
subtract 140 on both sides.
2x = 40
divide both sides by 2
x = 20
substitute x into the asked equation.
(20 + 27) = 47
47 is your answer.
To solve these problems you need to use the quadratic formula which is listed below.
So, if you take #2.
The
has a 1 in front of it. The x has a -3 in front of it. The last number is also -3. So:
a = 1
b = -3
c = -3
Then you can plug all of these into the equation and simplify. Which gives you:
Answer:
4:14, 6:21, 8:28
Step-by-step explanation:
2x2=4 2x7=14 = 4:14
2x3=6 3x7=21 = 6:21
2x4=8 4x7=28 =8:28
