Step-by-step explanation:
When folding up the box, x will be the height
(30-2x) will be the length
(25-2x) will be the width so
b. First, we can't have negative length or zero length so x must be Positve.
Set the other binomial equal to 0.
So our domain is
(0,12.5), meaning our value of x must be greater than 0 and less than 12.5
Answer:
5x=2x−4−2
Subtract 2 from −4 to get −6.
5x=2x−6
Subtract 2x from both sides.
5x−2x=−6
Combine 5x and −2x to get 3x.
3x=−6
Divide both sides by 3.
x= -6/3
Divide −6 by 3 to get −2.
x=−2
Step-by-step explanation:
If two triangles are similar then the
corresponding sides are in proportion. Thus,
AB / AU = BC / UV = AC / AV
AB / (20x+108) = 703 / 444
Where AB is equivalent to:
AB = AU + UB
AB = 20x + 108 + 273
AB = 20x + 381
Therefore going back to the first equation:
(20x + 381) / (20x + 108)
= 703/444
444 (20x + 381) = 703 (20x + 108)
8880x + 169164 = 14060x + 75924
14060x - 8880x = 169164 – 75924
5180 x = 93240
x = 93240 / 5180
