Formula for Perimeter is P=2l+2w. Then you plug in the information that you already know:
P=2(x+6)+2(12)
64=2x+12+24
64=2x+36
28=2x
x=14
you plug x back into your equation for l and get l=14+6=20
The length is 20 ft.
3/8. To get this answer you need to multiply the numerators and the denominators. 1 x 3 is equal to 3 and 2 x 4 is qual to 8. Therefore, 3/8
The interquartile range 21
<span>y = 3x² + 18x
factor out the leading coefficient
y = 3(x²+6x)
Complete the square
coefficient of the x term: 6
divide it in half: 3
square it: 3²
use 3² to complete the square:
y = 3(x²+6x + 3²) - 3·3²
= 3(x+3)² - 3·3²
= 3(x+3)² - 27
