An open box will be made from a rectangular piece of cardboard that is 8 in. by 10 in. The box will be cut on the dashed red lin
ANEK [815]
The correct answer is this one: "<span>C) 52 in3."
</span>
Given the illustration, we can be able to know the dimensions of the formed box.

The dimensions are
Length: 10 - 2x
Width: 8 - 2x
Height: x

So the volume is
Volume = (10-2x) * (8-2x) * (x)
Let x = 2.5
Volume = (5) * (3) * (2.5) = 37.5
Let x = 2
Volume = (6) * (4) * (2) = 48
Let x = 1.5
Volume = (7) * (5) * (1.5) = 52.5
Let x = 1
<span>Volume = (8) * (6) * (1) = 48
</span>Let x = 0.5
<span>Volume = (9) * (7) * (.5) = 31.5
</span>

Please help!! I'll give 30 points and brainliest.
Valentin [98]

Step-by-step explanation:

3 + \frac{9}{4} = \frac{9}{x+4} \\  \\  \therefore \: \frac{3 \times 4 + 9}{4} = \frac{9}{x+4}  \\  \\ \therefore \: \frac{12 + 9}{4} = \frac{9}{x+4}  \\  \\ \therefore \: \frac{21}{4} = \frac{9}{x+4} \\  \\ \therefore \:21(x + 4) = 36 \\  \\ \therefore \:21x + 84 = 36\\  \\ \therefore \:21x = 36 - 84\\  \\ \therefore \:21x = - 48\\  \\  \therefore \:x =  \frac{-48}{21} \\  \\ \therefore \:x =  \frac{-16}{7} \\  \\  \huge \red{ \boxed{ \therefore \:x = - 2 \frac{2}{7} }}\\  \\

What is the solution of the linear system of equations? please help
Mademuasel [1]
Sub for each other since both equals y
2x-3=y=2x+5
2x-3=2x+5
minus 2x oth sides
-3=5
false

no solution
(we can see that since slopes are same and y intercepts are differnt, the lines are paralell and therfor never intersect)
