Answer:
Step-by-step explanation:
let : x The length and y the width you have this system :
xy =60....(1)
x = y+10...(2)
put the value for x in (1): (y+10)y =60
the quadratic equation is : y² +10y - 60 = 0
Δ =b² - 4ac a = 1 b= 10 c= - 60
Δ =10² - 4(1)(-60) = 324 =18²
y 1 = (-10-18)/2 negatif...... refused
y 2 = (-10+18)/2 =4
the width is 4

Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
In this series we see that an extra two dots (one on the top, one on the bottom of the same column) are being added on the left side.
-> It starts out at 3
-> Next it becomes 5, with the extra two on the left side
-> Now it is 7, with the last set of extra two also on the left side
Using this logic, we can infer that the most likely answer will be A.
Have a nice day!

Atmospheric pressure = 101,325 Newtons / m²
Weight per meter square = 101,325 Newtons
Mass per meter square = 101,325 / (9.81 x 1000)
Mass per meter square = 10.3 tonnes per m²
