Answer:
Step-by-step explanation:
1. The formula for calculate th area of a square is shown below:
Where s is the side of the square.
2. Therefore, if the square tabletop has side lengths of (4x-8) units you have:
3. By definition, the square of a binomial is always a trinomial:
4. Then, you obtain:
The answer is most likely is 60.73
Answer:
Step-by-step explanation:
x^3 = -15
Answer: 75
Step-by-step explanation:
The area formula for a trapzoid is area= 1/2 (a+b) h
In this equasion, the substitution would be area=1/2 (10+15) 6
Following PEMDAS, enter the numbers within the parenthases (10+15)
Divide the 25 in half, then multiply by 6. This comes out to 75.
7x + 12 = 3(5x - 12)
Step 1: Distribute the 3 to the numbers in the parentheses (5x and -12)
7x + 12 = (3 × 5x) + (3 × (-12))
7x + 12 = 15x + (-36)
Step 2: Combine like terms
x's go with x's (7x and 15x)
Subtract 7x to both sides
(7x - 7x) + 12 = (15x - 7x) + (-36)
(0) + 12 = 8x - 36
12 = 8x - 36
Normal numbers go with normal numbers
Add 36 to both sides
12 + 36 = 8x + (-36 + 36)
48 = 8x
Step 3: Isolate x by dividing 8 to both sides
48/8 = 8x/8
6 = x
