23:8 is the simplest form. However, you can put 5.75:2 or even 2.86/1 if you are looking for the absolute simplest
1) <span>30x4 − 20x3 + 15x2
This is the answer to 1. Don't forget to rearrange the terms in ascending order. That can trip people up.
2) </span><span>x3 + 8x2 + 13
Don't forget to check the terms sign. The subtraction symbol switches them all. </span>
Use photo math!! it always gives me all the answers
<h3>
Answer: 65 square units</h3>
===============================================
Work Shown:
P = area of triangle
P = 0.5*base*height
P = 0.5*5*4
P = 10 square units
----------------
Q = area of square
Q = side*side
Q = 5*5
Q = 25 square units
----------------
R = area of trapezoid
R = height*(base1+base2)/2
R = 5*(7+5)/2
R = 5*12/2
R = 60/2
R = 30
----------------
T = total area of the entire figure
T = P+Q+R
T = 10+25+30
T = 65 square units
Answer: B represents 7
This problem is asking us to find halfway between 2 and 12.
[Method One]
12 - 2 = 10
-
10 / 2 = 5
-
2 + 5 = 7
<em>or</em>
12 - 5 = 7
[Method Two]
[Method Three]
We can count up from 2 and down from 12 until we hit the middle
2 12
3 11
4 10
5 9
6 8
7 7
