Answer:
x=4
Step-by-step explanation:
1. 7x+56=14x+28 using distributive property (with the number of stes you need to have, this may count as 2)
2. 56=7x+28 by subtracting 7x from each side
3. 28=7x by subtracting 28 from both sides
4. x=4 by dividng by 7
5. plug back into equation
7(4)+56=14(4+2)
28+56=14(6)
84=84
Step-by-step explanation:
CD = 6 cm because opposite sides are equal
angle d = 110
Perimeter is the total sum of the 4 sides.
The height is given as 8 inches. If this is doubled the new height becomes 16 inches. (The height increases by 8 inches)
total increase in perimeter = 8 + 8 = 16 inches.
Answer: 16 inches
The answer is subtraction
