Answer:
The area is 155 ft.
Step-by-step explanation:
To find the area if a trapezoid, you have to add the number on top( in this case 13 ft) and then add that with the bottom number(18 ft.) Then, you take that answer and divide it by 2. After that, multiply it with the height(10.) Thus, the answer is 155 ft.
15x - 12
Then you got X= 12/15
Answer:
x = -6
Step-by-step explanation:
Solve for x:
2 (3 x - 4) = 4 (x/2 - 8)
Put each term in x/2 - 8 over the common denominator 2: x/2 - 8 = x/2 - 16/2:
2 (3 x - 4) = 4 x/2 - 16/2
x/2 - 16/2 = (x - 16)/2:
2 (3 x - 4) = 4 (x - 16)/2
4/2 = (2×2)/2 = 2:
2 (3 x - 4) = 2 (x - 16)
Divide both sides by 2:
3 x - 4 = x - 16
Subtract x from both sides:
(3 x - x) - 4 = (x - x) - 16
3 x - x = 2 x:
2 x - 4 = (x - x) - 16
x - x = 0:
2 x - 4 = -16
Add 4 to both sides:
2 x + (4 - 4) = 4 - 16
4 - 4 = 0:
2 x = 4 - 16
4 - 16 = -12:
2 x = -12
Divide both sides of 2 x = -12 by 2:
(2 x)/2 = (-12)/2
2/2 = 1:
x = (-12)/2
The gcd of -12 and 2 is 2, so (-12)/2 = (2 (-6))/(2×1) = 2/2×-6 = -6:
Answer: x = -6
