Answer:
Width = x² + 5x - 4
Step-by-step explanation:
By the definition of an area model,
Area = Width × greatest common factor
Since, Area = 4x² + 20x - 16
And greatest common factor = 4
4x² + 20x - 16 = 4(Width)
By dividing both the sides of the equation by 4,

x² + 5x - 4 = Width
Therefore, width = (x² + 5x - 4) will be he answer.
Answer:
x= square root of 130
Step-by-step explanation:
a^2+b^2=c^2
a=7 b=9 c=x
49+81=x^2
130=x^2
square root of 130=x
Answer:
31
Step-by-step explanation:
Plug in 3 for x in the expression:
4(3²) - 5
Note that there are no parenthesis (other than the one I added, to make it easier for you. Follow the order of operations, PEMDAS. PEMDAS = Parenthesis, Exponents (& Roots), Multiplication, Division, Addition, Subtraction, and the left -> right rule.
First, solve the exponent:
4(3²) - 5 = 4(3 * 3) - 5 = 4(9) - 5
Next, solve the multiplication:
4(9) - 5 = 36 - 5
Finally, subtract:
36 - 5 = 31
31 is your answer.
