Answer:
see explanation
Step-by-step explanation:
Let u = x² ( choice of variable is flexible ), then
4u² - 21u + 20 = 0 ← expressed as a quadratic
This can now be solved for u and converted back into terms of x
Answer:

Answer:
The slope of the line that passes through these two points is 2/5
hope this helps ;)
Step-by-step explanation:
to find the slope (m) use the slope formula
m= y2-y1 / x2-x1
*plug in your points*
m= 4-2 / 3- -2 note here the <u>3- -2</u> changes to <u>3+2</u>
solve for m
m= 2/ 5
slope= 2/5
Shane and Karen want to measure the length of a soccer field. Length can be measured in different units such as cm, m ,km , yards etc. The question is asking us to select between two units cm or meters which will be more appropriate to measure the field.
To measure the field a larger unit is required. Meter is a bigger unit than centimeter.Centimeter is not the correct unit to measure the length of soccer field.
Shane and Karen should use meters to measure the soccer field.
