Step-by-step explanation:
Given expression:
(w)(3w + 5) = 0
Expand the parentheses;
3w² + 5w = 0
3w² = -5w
Divide both sides by w;
3w = - 5
w =

third side=√((√73)²-7²)=√(73-49)=√24
Answer:
<h3>
10, 12, 14</h3>
Step-by-step explanation:
Consecutive even integers increase by 2.
x ← an integer
2x ← an even integer (the smallest)
2x+2 ← next even integer consecutive to 2x (the middle one)
2x+2+2=2x+4 ← the last even integer consecutive to 2x+2 (the largest)
2(2x+2) ← twice the middle number
2x+2(2x+2) ← the sum of the smallest number and twice the middle
2x+4+20 ← 20 more than the largest number
2x + 2(2x + 2) = 2x + 4 + 20
2x + 4x + 4 = 2x + 24
-4 -4
6x = 2x + 20
-2x -2x
4x = 20
÷2 ÷2
2x = 10
2x+2 = 10+2 = 12
2x+4 = 10+4 = 14
