If x=width, then the equation would be:
x(x+10)=20,000
The length is 10 meters longer than the width(x), so the length is x+10.
To get the area(20,000) you multiply width by length, hence x(x+10).
Hope this helps.
Answer:
$10.50
Step-by-step explanation:
We can make an equation
2.50+2x=?
x=4 because we are riding 4 miles.
so it's 2.5+2*4=?
let's solve
2.5+8=$10.50
Answer:
11. -2
12. +0.5
Step-by-step explanation:
11. as x increases by 1, y decreases by 2, -2/1 = -2 the ROC is -2 (rate of change)
12. as x increases by 2, y increases by 1, 1/2 = 0.5, ROC is +0.5
