Answer:
8x⁴ - 7x³ + 12x
Step-by-step explanation:
=(4x⁴ + 7x + 5x³) + (8x⁴ + 6x³ - 3x)- (4x⁴ + 4x³ - 8x)
=4x⁴ + 7x + 5x³ + 8x⁴ + 6x³ - 3x - 4x⁴ - 4x³ + 8x
=4x⁴ + 8x⁴ - 4x⁴+ <em>5x³ + 6x³ - 4x³</em> + <u>7x - 3x + 8x</u>
=8x⁴ + 7x³ + 12x
Answer:
To calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. * i didnt know what to put so i put this*
Using proportions, it is found that the Pretty Pizza Company should open a new pizza place at any of the North or the South blocks.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.
The proportion of <u>pizza places per person</u> in each block of the town is given as follows:
- North: 32/(221 x 15) = 0.0096 < 1.
- South: 28/(22 x 150) = 0.0084 < 1.
Both proportions are less than 0.01, hence the Pretty Pizza Company should open a new pizza place at any of the North or the South blocks.
