The price of a notebook was

2 answers:

6 0

First you find the difference between the two prices:
3.80-3.30 = 0.50

Then you divide the Difference by the original price and times it by 100 to get the percentage increase:
0.50/3.30 = 0.1515
0.1515 * 100 = 15.15%

Hello this helps! :)

Complete the steps to factor the polynomial by grouping. P(x) = x3 + 5x2 – x – 5

ahrayia [7]

P(x) = x³ + 5x² – x – 5

P(x) = x²(x+5) - (x + 5)

P(x) = (x + 5)(x² - 1)

P(x) = (x + 5) (x + 1)(x -1)

Quick ! The perimeter of the rectangle below is 118 units. Find the length of side AD.

NARA [144]

Answer:

Step-by-step explanation:

the perimeter is all sides added up

therefore to solve for "z"

3z + 3z + 4z + 3 + 4z + 3 = 118

simplify

14z + 6 = 118

isolate z by first subtracting 6 from both sides and then dividing by 14 for both sides

z=8

plug z into side CB as AD and CB are congruent

3(8)

=24
