<h3>The length of rectangle is 12x³ metres .</h3>
As we know that
♦ Area of rectangle = Length × breadth
Substituting known values ,
⇒ 144x⁴ = 12x ( Length )
⇒ 144x⁴ / 12x = Length
⇒ 12x³ = Length
⇒ Length = 12 x³
Answer:
y=5x+13 is the answer
Step-by-step explanation:
so you have to use the y=mx+b method
you plug in 3 for y and -2 for x
3=5(-2)+b,
multiply 5 and -2 to get -10
and it should leave you with 3=-10+b
add -10 to both sides, 10 + 3= 13 and 13 is your b (which is your y-intercept)
13=B
Answer:
58kg, 70kg and 72kg
Step-by-step explanation:
Starting weight was 200.
Boy 1- Changed from 200 to 142. 200kg - 142kg= 58 kg
Boy 2- Changed from 142 to 72. 142kg- 72kg = 70kg
Boy 3- Last one on the scale and it showed 72kg so his weight is 72kg
