Yes they are the same.
When you add like terms:
8x - 14 = 8x + 5 - 19
8x - 14 = 8x - 14
The two sides equal the same thing.
2(3x+4) you multiply 2 times 3x and 2 times 4 which gives you 6x+8
7 centimeters
First, you have to set up an equation using the formula for area of a rectangle:
L x W = H. Then, plug in what you know: 8 x W = 56. Then, solve for x by dividing 56 by 8: W=7.
Answer:
The area is 15 cm^2.
Step-by-step explanation:
Step 1: Start with the given formula.
Step 2: Then replace l and w with the given measures.
Step 3: Then do the calculation.
Step 1: A = lw
Step 2: A = (3 cm) * (5 cm)
Step 3: A = 15 cm^2
Answer: The area is 15 cm^2.
