Here's [10] if you don't beat me to it by the time I finish typing:

9t^2 +12t + 4 = (3t      blank)(3t       blank)
= (3t  + 2)(3t + 2)

CHECK:
3t*3t + 3t*2 + 2*3t + 2*2
= 9t^2 + 6t + 6t + 4
= 9t^2 + 12t + 4

ANSWER: (3t + 2)(3t + 2)

Several students were asked how many blocks they walk from home to school each day. The results are shown in the line plot. How
serious [3.7K]

Answer:

25 students.

Step-by-step explanation:

A line plot is a simple graph that shows relationship among the values in a data using a number line.

From the line plot, each dot represents a student. While the number on the line shows the number of blocks walk each day by each student.

It can be deduced from the line plot that;

Only 1 student walks through 7 blocks, 2 walk through 5 blocks, 8 walk 4 blocks, 5 walk 3 blocks, 5 walk 2 blocks and 4 walk through 1 block to school each day.

So that;

1 + 2 + 8 + 5 + 5 + 4 = 25

Therefore, the number of students who took part in the survey is 25.
