Answer:
the answer is d
Step-by-step explanation:
Move the 150 to the left to get x^2+5x-150=0
Then factor to (x+15)(x-10)=0
The roots are -15 and 10
The positive root is 10
Answer:
A.20 ft
Step-by-step explanation:
the shadow is double the height of the object.
Answer:
The function rule be 100 × x
The independent variables i.e. (2, 3, and 4) are considered to be the domain
The dependent variable (200,300,400) are considered to be the range
Step-by-step explanation:
The computation is shown below:
As we know that
1 m = 100 cm
So
2 m = 200 cm
3 m = 300 cm
4 m = 400 cm
The function rule be 100 × x
The independent variables i.e. (2, 3, and 4) are considered to be the domain
The dependent variable (200,300,400) are considered to be the range
Answer:
length=30 ft breadth=20 ft
Step-by-step explanation:
let lenght be x then breadth will be 2/3x
now, area=lenght×breadth
=>600 =(x×2/3x)
=>600=2/3x^2
=>x^2=900
=>x=30 (ft)
now length will be 30 ft
breadth will be 30×2/3 (ft) =20(ft) ✌️
