8•13=104
7•13=91
6•13=78
104+91+78=273
Answer:
See below
Step-by-step explanation:
This is a piece-wise function.
4, -4≤ x ≤ -2
f(x) = 2, -2 ≤ x < 2
-3, 2 ≤ x ≤ 4
Answer:
x=3/4
Step-by-step explanation:
You need to isolate the variable. First subtract 3 from both side, then add 1x to both sides. You will end up with 1 1/3x=1. After that divide both sides by 1 1/3.
Hope you can understand the handwriting :)
Answer:
$4375
Step-by-step explanation:
Add up all the sides to get the perimeter:
240 + 285 + 450 + 450 + 450 = 1875 ft
Convert ft into yards:
3 ft = 1 yard
1875 ft = 625 yards
________________________________
(625 yards)($27) = $4375
