Answer:
80 square feet
Step-by-step explanation:
This time I will get it right for sure!
So first we need to find the area in feet, and then convert it in to inches.
1) Since the patio has the shape of a rectangle, then the formula is:
A = a * b
A = 20 * 16
A = 320 feet
2). Now we have to find the ratio, so:
320 / 4 = 80
So, the answer is
1 square inch to 80 square feet.
Hope this helps))
For this, use order of operations. your first step would be inside the parenthesis for the exponent. so now you have (4)^4. four to the fourth is 256, so your answer is 256!
Answer:
$15,249.64
Step-by-step explanation:
Depreciation means it is losing value.
Original price = 21,825
Depreciation rate (as a negative) = -5.8% or -0.058 as a decimal
Total duration n = 6
FV = Original price (1+r)^n
Next, plug in the numbers into the equation;
FV = 21,825 (1-0.058)^6
FV =21,825 *0.698723607
FV= 15,249.6427
5689767007---9889088-66=06=--666=--5543378784==
There is an error in the second step. Before cross multiplying the denominators, LCM of the values should be taken.
Step-by-step explanation:
Step 1; 1 - 
= 
.
By taking an LCM of x-2 on the LHS, we get
- = ,
as both terms on the LHS have same denominator, we can add them up,
= 
= .
Step 2; Now we cross multiply the denominators.
(x - 4) × (x + 2) = (x + 1) × (x - 2),
x² - 2x - 8 = x² - x - 2,
(x² - 2x - 8) - (x² - x - 2) = 0.
x² - x² - 2x + x - 8 + 2 = 0,
-x -6 = 0,
x = -6.
By simplifying the given expression, we get x = -6.
