I like to use Desmos Graphing Calculator. The attachment is what I get when I plug the inequalities in.
8*4=32
7*4=28
340÷32=10.625
350÷28=12.5
12.5-10.625= 1.875
Answer:

Step-by-step explanation:
<u><em>The question is </em></u>
Find the measure of the legs
we know that
In a 45 degrees -45 degrees -90 degrees triangle, the measure of the legs are equal

Applying the Pythagorean Theorem

solve for a

Divide by 2 both sides


Simplify

During a week:
Kevin works 3z during 5 days
kevin work (4z-7) during 1 day.
Kevin work 0 during 1 day.
z=unit time
f(z)= number of hours kevin works in one week.
f(z)=5(3z)+(4z-7)+0
f(z)=15z+4z-7
f(z)=19z-7
The number of hours kevin woirs in one week in terms of z is:
f(z)=19z-7
