Answer:
(3w - 7)(3w + 7)
Step-by-step explanation:
The expression is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
Thus
9w² - 49
= (3w)² - 7²
= (3w - 7)(3w + 7)
Answer:
The correct answer is:
In Step 1, the student should have used One-half x to represent Nadra’s age, and written the equation (x + 3) + x + one-half x = 33.
Step-by-step explanation:
Lets solve the problem step by step correctly
Let x be the age of Kareem
Let s be sadie's age
n be Nadra's age
According to "Sadie is 3 years older than Kareem"

And According to "Kareem is twice as old as Nadra"
x = 2n
n = x/2
Step 1: Writing the equation

Step 2: Solving the equation:

Step 3
Kareem's Age = 12
Sadie's Age = x+3 = 12+3 = 15
Nadra's Ade = 12/2 = 6
The student made the error in Step 1 where he wrote the equation.
Hence,
The correct answer is:
In Step 1, the student should have used One-half x to represent Nadra’s age, and written the equation (x + 3) + x + one-half x = 33.
