If you're trying to find the perimeter of a specific problem, you can add a file. To solve perimeter for any problem, you add all the side lengths. Hope that helps! :)
Hope i am not wrong
f(x)=4x+1
g(x)=x^2-5
(f-g)(x)=f(x)-g(x)
(f-g)(x) =4x+1-x^2+5
-(x^2-6-4x)
solve it for x
the answer for that question is 7 adults and 9 students
Answer:
x = 55
y = 45
Step-by-step explanation:
In similar triangles, the ratio between similar sides are the same. So,
AB/ED = BC/EF = AC/DF
Substitute values that they give
6/15 = 18/y = 22/x
Solve 6/15 = 18/y by cross-multiplying
6y = 15*18 = 324
Divide both sides by 6
y= 45
Solve 6/15 = 22/x by cross-multiplying.
6x = 22*15 = 330
Divide both sides by 6.
x = 55
Because there is some dispute between the answers, let's check the ratios.
6/15 = 18/45 = 22/55
0.4 = 0.4 = 0.4
True, x = 55 and y=45
Answer:
If in a 1:2:3 ratio, then
x + 2x + 3x = 180
6x = 180
x=30
Therefore, triangle must have angles of 30, 60, 90
