Answer:
let dimention of original garden be x
then (x-8)(x-5) = 180
x^2 -13x -140 = 0
(x-20)(x+7)=0
x= 20 or x = -7
x = 20
original area = (20)^2
= 400 m^2
Answer: X=3,1
The roots (zeros) are the x values where the graph intersects the x-axis. To find the roots (zeros), replace y with 0 and solve for x
Step-by-step explanation: Have a nice day
Multiply both sides by -3 to get rid of the negative and the fraction.
X - 3 = 21
Move the constants over to isolate the variable
X = 24
Answer:
The original cost is $19.55
Step-by-step explanation:
What we want to do here is calculate the final cost, given the original price
What we have to do here is to substitute the value of $23 for p
This we have as;
23-0.15(23)
= 23-3.45
= $19.55
Answer:
No
Step-by-step explanation:
f(x) = x²
f(3) = 3²
= 3 × 3
= 9 Not 16
also
√16 = 4
