Answer:
The communicative property shows how these problems should both work therefore they can both be answered by different equations
Step-by-step explanation:
Answer:
72 yd
Step-by-step explanation:
12 x 3=36
6 x 6=36
36 + 36= 72
Answer:
An equation which has the same solution as the given equation is:
( x - 18 ) ( x + 2 ) + 48 = 0 ....
Step-by-step explanation:
The given expression is:
x2-16x+12
Break the constant term:
x^2-16x-36 +48=0
[x^2-16x-36] +48=0
Now break the middle term inside the brackets
(x^2-18x+2x-36)+48=0
Take the common
[x(x-18) +2(x-18)]+48=0
(x-18)(x+2)+48=0
Thus an equation which has the same solution as the given equation is:
( x - 18 ) ( x + 2 ) + 48 = 0 ....
In reference to the angle of elevation (41 degrees), the adjacent side is 60 and the opposite side is the unknown.
Using tangent ratio:
tan 41 = opp/60
60 tan41 = opp
opp side = 52.2yards

Answer:
A whole number with 4 digits is always greater than a whole number with 3 digits.
This requires that both numbers be positive.
Explanation.
In the decimal system, we count 0,1,2, ..., 9 (1st digit).
When we reach 10, we shift left and count in tens from 10,20,30, ..., 90 (2nd digit).
When we reach 100, we shift left and count in hundreds from 100,200,300, ..., 900 (3rd digit).
Then we count in thousands as 1000,2000, ... ( 4th digit).
Because the 4th digit counts in thousands and the 3rd digit counts in hundreds, a whole number in the 4th digit will be greater than a whole number in the 3rd digit.
