Answer:
4
Step-by-step explanation:
HK is double of HW, so: ![42=2(x^2+5)](https://tex.z-dn.net/?f=42%3D2%28x%5E2%2B5%29)
Then solve. Divide both sides by 2.
21=x²+5
16=x²
4=x
I hope this helps and good luck on the rest of your HW
Your answer is C because it says the least value the variable k can be is 12 so, it can be 12 and less. So 12 is included in the variables k could be.
Hope that helps you understand. :3
Answer:
A. A = (3w - 5) * w
B. 2 feet squared
Explanation:
A. The length is 5 less than 3 times the width. To write the rule for this, you’d subtract 5 from 3 times the width (3w - 5). The area is the length times the width so the rule would be:
A = (3w - 5) * w
——————————
B. Plug in 2 for w using the given rule.
A = (3[2] - 5) * (2)
Distribute
(6 - 5) * 2
Subtract 5 from 6
1 * 2 = 2
The answer is 2 feet squared since this is area.
Exactly what you just said 1:19
