Answer: the width of the border is 2 inches.
Step-by-step explanation:
The formula for determining the area of a rectangle is expressed as
Area = length × width
Let x represent the width of the border.
The photo is printed on an 12-inch by 18-inch piece of paper. The width of the photo will be (12 - 2x) inches. The length of the paper will be (18 - 2x) inches.
The area of the paper would be
(18 - 2x)(12 - 2x)
The photo covers 112 square inches and has a uniform border. This means that
(18 - 2x)(12 - 2x) = 112
216 - 36x - 24x + 4x² = 112
4x² - 60x + 216 - 112 = 0
4x² - 60x + 104 = 0
Dividing through by 4, it becomes
x² - 15x + 26 = 0
x² - 13x - 2x + 26 = 0
x(x - 13) - 2(x - 13) = 0
x - 2 = 0 or x - 13 = 0
x = 2 or x = 13
The only possible value for the width of the border is x = 2 inches
Answer:
96
Step-by-step explanation:
First divide 360 by 2.
Then divide 180 by 5 and that is how many 5 pound bags he will use.
Then divide 180 again by 3 and that is how many 3 pound bags he will use.
Answer:
-16,-6,4,14,24
Step-by-step explanation:
First thing first, we need to alter this equation is y is the value we are fining. we can do this by adding 10x to both sides. our new equation is
y=10x+4
Now, all we have to do is plug in out x values in order to get our y values and complete the table.
Example, 10x2 is 20 and 20+4 is 24 so when x is 2, y is 24
X=-12.52
The reason why is because to get x by itself we have to get rid of 15.09, so we subtract 15.09 from both sides and 2.57-15.09=-12.52
Hope this helps!
