A=lw

w=width

2w+5=length

42=w(2w+5)

42=2w2+5w

2w2+5w-42=0

use the quadratic equation

(-5+√25+336)/4

(-5+√361)/4

(-5+19)/4

14/4=3.5

w=3.5 m

2w+5=12 m

3.5 by 12 rectangle

Yes its math y=7x+6 that is one of the questions
8_murik_8 [283]

Answer:

See explanation below.

Step-by-step explanation:

The equation is:

y = 7x + 6

This is the equation of a line in slope intercept form. The general form, where m is the slope and b is the y intercept is:

y = mx + b

In this case, with the equation:

y = 7x + 6

m is 7 and the y intercept is 6.

The y intercept means the point when x = 0:

(0, 6) is the y intercept point on the graph.

The freezing point of water is 32º F. Tim added potassium and found
HACTEHA [7]

Answer:

The freezing point of the water with the added potassium is 24 degrees Fahrenheit.

Step-by-step explanation:

To find the freezing point of the water with the added potassium, you need to subtract 8 degrees from the initial freezing point of water, This is because you know that after adding potassium to water, the freezing point went down by 8 degrees Fahrenheit. So you need to subtract 8 degrees from the initial freezing point of water (32 degrees Fahrenheit). 32º F - 8º = 24º F. So the freezing point of the water with the added potassium is 24 degrees Fahrenheit.
