Answer:
2x^2 +4x +4
Step-by-step explanation:
5x ^2 - 3x + 8 - (3x ^2 -7x + 4)
Distribute the minus sign
5x ^2 - 3x + 8 - 3x ^2 +7x - 4
I like to put them vertically
5x ^2 - 3x + 8
- 3x ^2 +7x - 4
-----------------------
2x^2 +4x +4

Answer:
We know that the rectangular plate has measures of:
length = 7.6 ± 0.05 cm
width = 3.1 ± 0.05 cm
(the error is 0.05cm because we know that both measures are correct to one decimal place)
First, the upper bound of the length is equal to the measure of the length plus the error, this is:
L = 7.6 cm + 0.05 cm = 7.65 cm
The upper bound of the area is the area calculated when we use the upper bound of the length and the upper bound of the widht.
Remember that the area for a rectangle of length L and width W, is:
A = W*L
Then the upper bound of the area is:
A = (7.6cm + 0.05cm)*(3.1cm + 0.05cm) = 10.8 cm^2
