Answer:
number 4 is $223.6 (ADD THE MONEY SYMBOL TOO)
Step-by-step explanation:
44.72 = tip + money she gets per unit of time
then 44.72 x 5 because 5 is how many hours and 44.72 is how much she gets an hour
So, for this kind of problem you need to FOIL.
This stands for:
F- first
O-outer
I-inner
L-last
What this means is that:
step 1- multiply the FIRST terms in each thing. So for example in problem 6 of the problems you sent it would be x times x. =
step 2- multiply the OUTER terms in each thing. So for example in problem 6, it would be x times 3. =3x
step 3- multiply the INNER terms in each thing. So for example in problem 6, it would be 6 times x. =6x
step 4- multiply the LAST terms in each thing. So for example in problem 6, it would be 6 times 3. =18
step 5: you add all of your products. So for problem 6 it would be y=
+ 9x +18.

The largest angle is 5/9 of the total which in a triangle is 180 degrees
5/9 x 180 = 100 degrees
The perimeter means you add up all the sides
so you do
(12b-8) + (12b-8) + (9b+8)
now you just add the like terms
12b+12b+9b = 33b
-8+-8+8= -8
so the perimeter is 33b-8
