Answer:
20 feet
Step-by-step explanation:
Parimeter is how far you would walk if you made a lap around the shape, walking on the edge lines like a balance beam.
To find perimeter, we need to add up all the sides.
Because it's a square each side has the same length.
There are 4 sides.
5 x 4 = 20
or 5 + 5 + 5 + 5 = 20
The perimeter is 20 feet
The sum of the polynomials is -4x^2 -11x-5.
The error Giovanna made in her calculation is multiplying 7 by 2 and adding with 5/8(step 3)
<h3>Fraction</h3>
Her calculation:
- 7 (2 and StartFraction 5 over 8 EndFraction): 7(2 5/8)
- 7 (2 + StartFraction 5 over 8 EndFraction): 7(2 + 5/8)
- 14 + StartFraction 5 over 8 EndFraction: 14 + 5/8
- 14 and StartFraction 5 over 8 EndFraction: 14 5/8
Her error was multiplying 7 by 2 and adding with 5/8(step 3)
Correct calculation:
7(2 + 5/8)
= 14 + 35/8
= (112+35) /8
= 147/8
= 18 3/8
