80 points!!! I desperately need help! tell me how to do this! PLZ(4k+5)(k+1)=0
2 answers:
Lets solve your equation step by step:
(4k + 5)(k + 1) = 0
Step 1: Simplify both sides of the equation:
4k^2 + 9k + 5 = 0
Step 2: Factor left side of equation:
(4k + 5)(k + 1) = 0
Step 3: Set factors equal to 0:
4k + 5 = 0 or k + 1 = 0
k = - 5/4 or k = - 1
Answer: k = - 5/4 or k = - 1
Hope that helps!!!! ( Answer: k = -5/4 or k = -1)
Use distributive property to get 4k^2 +9k+5 and factor it from there. You should get (4k+5)(4k+4).

the second option!
Step-by-step explanation:
![5+2n=? \\ n= \frac{3}{4} \\ 5+ \frac{2*3}{4}= 5+ \frac{6}{4}= \frac{5*4}{4} + \frac{6}{4}= \frac{20+6}{4}= \frac{26}{4}= \frac{13}{2}=6,5](https://tex.z-dn.net/?f=5%2B2n%3D%3F%20%5C%5C%20n%3D%20%5Cfrac%7B3%7D%7B4%7D%20%5C%5C%205%2B%20%5Cfrac%7B2%2A3%7D%7B4%7D%3D%205%2B%20%5Cfrac%7B6%7D%7B4%7D%3D%20%5Cfrac%7B5%2A4%7D%7B4%7D%20%2B%20%5Cfrac%7B6%7D%7B4%7D%3D%20%5Cfrac%7B20%2B6%7D%7B4%7D%3D%20%5Cfrac%7B26%7D%7B4%7D%3D%20%5Cfrac%7B13%7D%7B2%7D%3D6%2C5%20%20%20%20%20)
So the value of 5+2n is n=3/4 is 6,5
