(-2^3) = -8.
-2 times 3 = -6.
The expression is now -6 - (-8).
-6 + 8 = 2.
The answer should be 2.
Answer:
r
Step-by-step explanation:
If x is the amount that Tanya paid for each item, then Tony's items would be x-2.25. So:
3x=4(x-2.25)
3x=4x-9
x=9
x-2.25=6.75
Tanya spent $9 on each item; Tony spent $6.75 on each of his items. ☺☺☺☺
Hey there Caleb!
To start of, the sentence was clear on that it said . . .
The statement listed above is the (key) point. We need to keep this in mind.
So, now that we know this.
We would use the mathematic (Ф)
So,sense we know that a (hexagon) had it's (6) shapes, we would do
. . .
Ф = 360° : 6 = 60°
Your correct answer to this question would be
. . .
Hope this helps.

Step-by-step explanation:
We can prove the statement is false by proof of contradiction:
We know that cos0° = 1 and cos90° = 0.
Let A = 0° and B = 90°.
Left-Hand Side:
cos(A + B) = cos(0° + 90°) = cos90° = 0.
Right-Hand Side:
cos(A) + cos(B) = cos(0°) + cos(90°)
= 1 + 0 = 1.
Since LHS =/= RHS, by proof of contradiction,
the statement is false.
