T=60+7x
x is for numbers of hours worked
t stands for total pay
Lets do this week by week
beginning pressure 45 pounds
end of week 1
45 *.06 = 2.7
45 - 2.7 = 42.3
end of week 2
42.3 * .06 = 2.538
42.3 - 2.538 = 39.762
end of week 3
39.762 *.06 = 2.38
39.762 - 2.38 = 37.37
end of week 4
37.37* .06 = 2.2425
37.37628 - 2.2425= 35.12
end of week 5
35.12 * .06 = 2.107
35.12 - 2.107 = 33.012
end of week 6
33.012* .06 = 1.98
33.012 - 1.98 =31.03
Here is the fast way to get to this answer.
do 1-.06 = .94
then do
45(.94)(.94)(.94)(.94)(.94)(.94) = 31.04
The area of the larger square is x^2
The area of the small square is 3*3 = 9
To find the area of the shaded region you subtract the two values.
x^2 - 9
The factored form of this is (x + 3)(x - 3)
(x-6)(x+2)=0
x-6=0, x=6
x+2=0, x=-2
least -2, greatest 6
Answer:
B
Step-by-step explanation:
We have to find which trinomial has:
1) two terms that are the perfect square of two numbers
2) a terms that is the double product of the two numbers
the first condition is satisfied by A and B, but only B satisfied the second., in fact the trinomial can be rewrite as: (2a-5)^2
Options C and D are traps because the square of a number can’t be negative
