Define the length and the width of the rectangle
length = 5x + 4
width = 3x + 2

Determine the area
area = length × width
area = (5x + 4) (3x + 2)
area = (5x)(3x) + 2(5x) + 4(3x) + (4)(2)
area = 15x² + 10x + 12x + 8
area = 15x² + 22x + 8

The area of the rectangle is (15x² + 22x + 8) units²

Joshua uses the escalator in the shopping mall to get to the ground floor from the underground garage located at (12,-5). Which
alina1380 [7]

Answer:

(4,5)

Step-by-step explanation:

Initial location of Joshua in the shopping mall is expressed according to the coordinate (12, -5)

If he undergoes a translation of 8 steps to the left and 10 steps upwards, this means that he moves 8 steps towards the negative x axis and 10 steps towards the positive y axis. The new coordinate will be gotten by adding the translation (-8, 10) to the initial coordinate as shown

New position = (12, -5) + (-8,10)

New position = (12-8, -5+10)

New position = (4, 5)

Hence the coordinates that corresponds to the location of the ground floor when undergoing a translation of 8 steps to the left and 10 steps upwards will be (4,5)

At SMS, 25% of the teachers teach math. If there are 50 math teachers, how many teachers are there all together at SMS?
algol [13]

Answer:

200

Step-by-step explanation:

25 percent is known to be 1/4 of a number, so if 50 teachers represent 1/4 of all the teachers, that means that in order to get a full number, we must multiple 50 by 4 in order to get all 100% of the teachers.

By doing 50x4, we can conclude that 200 teachers teach at the school (aka 100% of all teachers)
