Theres nothing there, it's just the question
Answer:
Hello! answer: 432
Step-by-step explanation:
12 × 8 = 96
12 × 8 = 96
12 × 6 = 72
12 × 6 = 72
8 × 6 = 48
8 × 6 = 48
Then you add them all up so...
96 + 96 + 72 + 72 + 48 + 48 = 432 therefore the surface area is 432 hope that helps!
x =-5

1) Since the Formula of the Midpoint is:
2) So Let's plug it into the formula the values, for A, and B
3) So the x coordinate of the Midpoint is x =-5
The formula of an area of trapezoid:
![A=\dfrac{base_1+base_2}{2}\cdot height](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7Bbase_1%2Bbase_2%7D%7B2%7D%5Ccdot%20height)
We have:
![base_1=3ft+4ft=7ft\\\\base_2=3ft\\\\height=3ft](https://tex.z-dn.net/?f=base_1%3D3ft%2B4ft%3D7ft%5C%5C%5C%5Cbase_2%3D3ft%5C%5C%5C%5Cheight%3D3ft)
Substitute:
![A=\dfrac{7+3}{2}\cdot3=\dfrac{10}{2}\cdot3=5\cdot3=15\ ft^2](https://tex.z-dn.net/?f=A%3D%5Cdfrac%7B7%2B3%7D%7B2%7D%5Ccdot3%3D%5Cdfrac%7B10%7D%7B2%7D%5Ccdot3%3D5%5Ccdot3%3D15%5C%20ft%5E2)
The perimeter:
![P=3+4+5+3+3=18\ ft](https://tex.z-dn.net/?f=P%3D3%2B4%2B5%2B3%2B3%3D18%5C%20ft)
Answer:

Step-by-step explanation:
The absolute value always returns a positive result, however the expression inside can be positive or negative, that is
4x - 1 = 7 OR 4x - 1 = - 7
4x - 1 = 7 ( add 1 to both sides )
4x = 8 ( divide both sides by 4 )
x = 2
OR
4x - 1 = - 7 ( add 1 to both sides )
4x = - 6 ( divide both sides by 4 )
x =
= -
= - 1.5
Solutions are x = - 1.5 or x = 2
