Answer:
x + 4
Step-by-step explanation:
Given
→ x ≠ 4
Factor the difference of squares on the numerator
x² - 16
= x² - 4² = (x - 4)(x + 4), thus expression becomes
= 
← cancel (x - 4) on numerator/ denominator
= x + 4
Answer:
The width of the logo need to be 15 cm.
Step-by-step explanation:
Since the logo is a rectangle, it's area is given by the product of the width and the length.
Area = width*length
Since the width is an unkown value we will call it "x" and the length is twice the width so it'll be "2*x". The area of the logo is:
Area = x*(2*x) = 2*x²
In order to have a patch that is 450 cm² we need:
2*x² = 450
x² = 450/2 = 225
x = sqrt(225) = 15 cm
The width of the logo need to be 15 cm.
