Insert brackets to make this calculation right 4x2+5-3=
pentagon [3]
Salutations!

Insert brackets to make this calculation right 4x2+5-3

The brackets should be inserted outside 2+5. If you add brackets outside teh rest of the numbers the calculation would not make sense.

4 × (2 + 5) - 3

Hope I helped (:

have a great day!

Plz help.<br><br> Find the perimeter of the window to the nearest tenth.
Stels [109]
Let's solve this problem step-by-step.

STEP-BY-STEP EXPLANATION:

First, we will establish that the shape of the window is a semi-circle. This means we must use the formula for the perimeter of a semi-circle to obtain the perimeter of the window.

The formula for the perimeter of a semi-circle is as follows:

Let perimeter of window or semi-circle = P

P = [ 2( Pi )r / 2 ] + 2r

Where r = radius of circle or semi-circle

From this, we will simply use the value of the radius given from the diagram in the problem and substitute it into the formula to obtain the perimeter of the window.

P = [ 2( Pi )r / 2 ] + 2r

r = 20

THEREFORE:

P = [ 2( Pi )( 20 ) / 2 ] + 2( 20 )

P = 20( Pi ) + 40

P = 102.83...cm^2

P = 102.8cm^2 ( to the nearest tenth )

FINAL ANSWER:

Therefore, the perimeter of the window is 102.8cm^2 ( to the nearest tenth ).

Hope this helps! :)
Have a lovely day! <3
