Part A: Describe the two factors in this expression. (4 points) The factors are (1) the constant coefficient 9 and (2) the binomial (7+2x).
Part B: How many terms are in each factor of this expression? (4 points) The first factor (multiplicand), 9, has one term. The second factor (multiplicand), (7+2x), has two terms (and is thus called a binomial).
Part C: What is the coefficient of the variable term? (2 points) The only such coefficient is 2.
Answer:
Where is the equation for me to solve for x?
Step-by-step explanation:
----------------------------------------
Define x:
----------------------------------------
Let x be the length of the pool.
Length of the pool and its border = x + 1 + 1
Length of the pool and its border = x + 2
----------------------------------------
Given area = 361 ft², find x:
----------------------------------------
(x+2)² = 361
x+ 2 = √361
x + 2 = 19
x = 19 - 2
x = 17
----------------------------------------
Find Length of the pool:
----------------------------------------
Length of the pool = x = 17 feet
----------------------------------------
Find Area of the pool:
----------------------------------------
Area = 17 x 17
Area = 289 ft²
------------------------------------------------------------
Answer: Area of the pool = 289 ft²
------------------------------------------------------------
R=2.1
Diameter would be half of that
Algebra Examples
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values.
