Using the distance formula, the length of WX is approximately: 8.5.
<h3>How to Find the Length of a Segment Using the Distance Formula?</h3>
Distance formula is, .
Given the endpoints:
W(5,-3) = (x1, y1)
X(-1,-9) = (x2, y2)
Plug in the values:
WX = √[(−1−5)² + (−9−(−3))²
WX = √[(−6)² + (−6)²]
WX = √72
WX ≈ 8.5

Answer:
9x² + 28x - 32
Step-by-step explanation:
Given
(9x - 8)(x + 4)
Each term in the second factor is multiplied by each term in the first factor, that is
9x(x + 4) - 8(x + 4) ← distribute both parenthesis
= 9x² + 36x - 8x - 32 ← collect like terms
= 9x² + 28x - 32
The answer is $60.50, if the 10% is coming from the $55
Let's see..
? * ? = 28
Well, we know:
5 * 5 = 25
6 * 6 = 36
It must be closer to 5, yet much smaller than 6.
Same need help too has any one answers it fro you. yk
