Answer:
yup your answer is right
Step-by-step explanation:
two x solutions are <u>+</u>2√3
<u>+</u>2√3 can be written as +2√3 or -2√3
Area of a trapezoid: [(top +bottom)*height]/2
suppose the length of one base is x, then the other base is 5x-19
[(x+5x-19)*18]/2=477
[6x-19]*18=954
6x-19=53
6x=72
x=12
The longer base is 5*12-19=41
Answer:
n = 15
Step-by-step explanation:
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation: 3*(n-6)-(27)=0
Pull out like factors : 3n - 45 = 3 • (n - 15)
Then: 3 • (n - 15) = 0
It's pretty easy from there, good luck!
