Answer:
x = 50
Step-by-step explanation:
In a parallelogram, consecutive angles are supplementary, thus
∠ A + ∠ B = 180 , substitute values
2x + 2x - 20 = 180
4x - 20 = 180 ( add 20 to both sides )
4x = 200 ( divide both sides by 4 )
x = 50

Answer:
120
Step-by-step explanation:
the formula of a box is L x W x H
so since the length is 6 and the width is 4 and the height is 5 you multiply
6x4x5=120
Answer:
1.) True, because it says three times so you know the x belongs there. Also, you have to follow the order of what the problem says.
2.) False, because it is not in the order of how the problem states it.
3.) False, because if you transfer the fraction to a decimal you get 4.333333. It's not valid.
4.) True, because if you do 7 × 3, it equals to 21. So, 21 - 17 = 4. And Jenny is supposed to have 4 quilts.

Answer:
x = 18 cm
y = 9 cm
Step-by-step explanation:
An open-top box will have minimum surface area when it is in the shape of half a cube. The whole cube would have volume 2×2916 = 5832 cm³, so its side length would be ∛5832 cm = 18 cm.
The dimensions of the box are x = 18 cm; y = 9 cm.
__
The surface area is x^2 +4xy, where y = 2916/x^2. That is, the surface area is ...
S = x^2 +11664/x
Setting the derivative to zero, we find ...
dS/dx = 0 = 2x -11664/x^2
x^3 = 5832 . . . . . . . . may look familiar
x = ∛5832 = 18
y = 2916/18^2 = 9
