Answer:
a ≈ 1.8
Step-by-step explanation:
a / sin (180 - 105 - 15)° = 2 /sin 105°
a = (2 /sin 105°) x sin 60°
a = (2 / 0.97) x 0.87
a = 1.79 (≈ 1.8)
Answer:
Step-by-step explanation:
Do FOIL, first outside inside last
3x × 3x = 9x^2
3x × -7 = -21x
7 × 3x = 21x
7 × -7 = -49
So it would just be 9x^2 - 49
Answer:
10x + 2y - 20
Step-by-step explanation:
Bill = 4b + 2.
Ron = 8b - 5.
Bill + Ron = (4b + 2) + (8b - 5).
= 4b + 8b + 2 - 5.
= 12b - 3.
That's the expression for the total number of blocks used by both Bill and Ron.
There are several information's already given in the question. the answer can be easily deduced using those information's.
Mean = (27 + 27 + 28 +29 + 32 + 33 + 34)/7
= 210/7
= 30 mpg
From the above deduction, it can be concluded that the correct option among all the options that are given in the question is the third option or option "C". I hope that this is the answer that you were looking for and it has come to your desired help.
