Hey There!! ~
The answer to this is: the upper bound for the length is Lower and Upper Bounds
The lower bound is the smallest value that will round up to the approximate value.
The upper bound is the smallest value that will round up to the next approximate value.
Ex:- a mass of 70 kg, rounded to the nearest 10 kg, The upper bound is 75 kg, because 75 kg is the smallest mass that would round up to 80kg.
Here , A length is measured as 21cm correct to 2 significant figures. We need to find what is the upper bound for the length . let's find out:
As discussed above , upper bound for any number will be the smallest value in decimals which will round up to next integer value . So , for 21 :
⇒
21.5 cm on rounding off will give 22 cm . So , the upper bound for the length is
Hope It Helped!~

I don’t really know let me ask my friends 1
3 x 5 = 15 + 12= 27 and there is your answer!
Answer:
7x + 9
Yes they are equivalent
Step-by-step explanation:
The first expression given to us is
2x + 3 + 5x + 6
Let us call it equation (i)
Now we have to find equivalent expression to it
the given equation is 2x + 3 + 5x +6
similar terms are terms involving x and not involving x
so solving the equation gives
2x + 5x + 3 +6
= 7x + 9
Now we have two equations one is
2x + 3 +5x + 6 ...............(i)
Other is
7x + 9 ..............(ii)
To check they are equivalent or not
Put x = 3 in equation (i)
2(3)+3+5(3)+6= 6 + 3 + 15 + 6
=30
Now put x=3 in second equation
7(3)+9=21 + 9
=30
As the answer of both the equations are 30 so they are equivalent
Answer:
Area of the shaded region =
Step-by-step explanation:
Area of the Shaded region= Area of rectangle - Area of the triangle
Area of the rectangle= Length * breadth
Putting the values in the formula
Area of the rectangle :
Area of the Triangle =
Base of triangle= 20 inches , Height of the triangle = 10 inches
Area of triangle
Area of the shade region:
