Answer:
$256.75
Step-by-step explanation:
$178 + $98.25 = $276.25
$276.75 - $19.50 = $256.75
The average is:
105 cm
1 m = 100cm
2m = 2*100 = 200cm
then:
(200 + 20 + 95)/3 = 315/3 = 105cm
Given expression:
(w)(3w + 5) = 0
Expand the parentheses;
3w² + 5w = 0
3w² = -5w
Divide both sides by w;
3w = - 5
w =
