Combine like terms.
6A*7A = 42A
3B*7B = 21B
Now we have our most simple expression:-
21B*42A
Answer:
176 mm
Step-by-step explanation:
The circumference of a circle is the perimeter of a circle (length of a circle). The circumference of a circle is given as:
Circumference (C) = 2πr = πd, where d is the diameter
The circumference of a circle with diameter 7 mm is:
C = πd = 22/7(7) = 22 mm
The length of the paper to round the cylindrical pencil is the same as the perimeter of the pencil which is 22 mm.
To round the pencil 8 times, the length of the paper needed = 8 × 22 mm = 176 mm
Answer:
1. 3(2)+(4)-(4)=6
2. 2(8)-3(8)+4= -4
3. 4-16-16= -28
Step-by-step explanation:
Answer:
The value of is 432.
Step-by-step explanation:
Let be the following system of equations:
(1)
(2)
Then, we solve both for and :
From (1):
(1) in (2):
The roots of the polynomial are determined by the Quadratic Formula:
By (1):
If we know that and , then the final value is:
The value of is 432.
