Answer:
11.19ft * 15.19ft
Step-by-step explanation:
Width = x
Length = x-4
Area = 170ft2
Area of a rectangle = Length * Width
170ft^2 = (x-4) * x
x(x-4) = 170...........equation(1)
x^2-4x-170 = 0......equation(2)
Using the quadratic equation(for equation 2),
-b+-sqrtb^2-4ac/2a
from equation(2): a=1x=1
b= -4
c= -170
thus, x= 4 + sq.rt696/2 = 4 +26.38 =30.38/2=15.19
The answer is the orange square 20
Answer:
a) 5 x² + 3 x -10
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given polynomials
3 x² - 5 x + 1 and 8 x² - 2 x -9
Given that
3 x² - 5 x + 1 From 8 x² - 2 x -9
⇒ 8 x² - 2 x -9 - ( 3 x² - 5 x + 1 )
= 8 x² - 2 x -9 - 3 x² + 5 x - 1
= 5 x² + 3 x -10
