Answer:
l = (S - 2wh)/(2w + 2h)
Step-by-step explanation:
S = 2lw + 2wh + 2hl
S - 2wh = 2lw + 2hl
S - 2wh = l (2w + 2h)
(S - 2wh)/(2w + 2h) = l
Answer:x=750
Step-by-step explanation:
2/3(x)+ 1/4(x) + 375
(9/12)x - (3/12)x = 375
(6/12)x + 375
Answer: it is the first one
Step-by-step explanation:
To simplify x^2-3 =5x
You would first subtract 5x from both sides
X^3-5x-3
Next you would plug this into the quadratic equation:
X=5+/- the square root of: -5^2 -4(1)(-3)/2(1)
Then simplify,
5+/- the squareroot of 24 + 12 / 2
5+/- The squareroot of 36 /2
5+/- 6 / 2
Then solve if it’s an addition or subtract
5+6/2
X=11/2 or 5 1/2
5-6/2
X= -1/2
The answer is x=-1/2 or x=11/2
Hope this helps
