Set each expression from the parentheses equal to 0 separately like so:
Equation 1: x - 4 = 0
Equation 2: -5x + 1 = 0
Now for each equation solve for x!
Equation 1:
x +(- 4 + 4) = 0 + 4
x = 4
Equation 2:
-5x +( 1-1) = 0 - 1
-5x/ -5 = -1 / -5
x = 1/5
Check:
(4 - 4)(-5*4 + 1)
(0) (-20 + 1)
(0) (-19)
0 = 0 -------------------------> correct!
(1/5 - 4)(-5 * 1/5 + 1)
(-19/5)(-1 + 1)
(-19/5)(0)
0 = 0 -------------------------> correct!
smaller x = 1/5
larger x = 4
Hope this helped!
Answer:
Step-by-step explanation:
Conditions
- A diameter must be chosen such that it meete the sidewalk perpendicular to itself.
- The diameter meets the sidewalk at the sidewalk's midpoint.
- The diameter meets the sidewalk such that the diameter is cut into two segments 30+18 and 12
- The sidewalk is cut in 1/2 where the diameter meets the sidewalk as the diagram shows.
- If all these conditions are met, the relationship between the four lines is
Equation
48/12 = x^2
Solution
4 = x^2
sqrt(x^2) = sqrt(4)
x = 2
The length of the sidewalk is 4. Why is it doubled.
Because there are 2 xs of equal length
Angle 4 = Angle 5 = 42⁰( alternate interrior angle)

Answer:
5280
Step-by-step explanation:
if u times them all up first u get 60 times 11 witch = 660 and then i times 660 and 8 to get 5280
