Answer:
x = (74-28)/2
Step-by-step explanation:
We find the perimeter of a triangle by adding the sides together
s1 +s2+s3 = P
The perimeter is 74
s1 +s2+s3 = 74
We know one of the sides is 28
28 +s2+s3 = 74
The other two sides are equal in length, call them x
28 +x+x = 74
Combine like terms
28+2x = 74
We want to solve for x
Subtract 28 from each side
28-28+2x = 74-28
2x = 74-28
Divide each side by 2
2x/2 = (74-28)/2
x = (74-28)/2
Answer:
c = -4
Step-by-step explanation:
If f(x) = 2x^3 - x + c and f(2) = 10, plug in 2 for the x values in the function and make the function output 10.
10 = 2(2^3) - 2 + c Now, we only have to deal with one variable, that is c.
10 = 2(8) - 2 + c
10 = 16 - 2 + c
10 = 14 + c
-4 = c After simplifying, we get that c is -4.
To check this, plug in 2 for x, and -4 for c in the function. If the function produces 10 as the result, the halleluja!
f(2) = 2(2^3) - 2 - 4
f(2) = 2(8) - 2 - 4
f(2) = 16 - 2 - 4
f(2) = 10
