I’m not entirely sure but i think it might be s=lb^2 because the l, b, and b are all being multiplied together, and since you are multiplying and not adding the b’s, the two would go to b^2, and then you just multiply by l to get lb^2
First, substitute 6 in for x:
5 x 6^2 + 6 - 7
Simplify:
30^2 + 6 - 7
30^2 + 1
900 + 1
901
Hope this helps!!
Answer: x = 3 ± 4i
<u>Step-by-step explanation:</u>
x² - 6x + 25 = 0
a=1 b= -6 c=25
Use Quadratic Formula:






= 3 ± 4i
