Answer:y74
Step-by-step explanation:
Answer:
14/9 or 1.555556
Step-by-step explanation:
1) Simplify 1 + 1/3 to 4/3.
(4/3)^2 - 2/9
2) Use Division Distributive Property: (x/y)^a = x^a/y^a.
4^2/3^2 - 2/9
3) Simplify 4^2 to 16.
16/3^2 - 2/9
4) Simplify 3^2 to 9.
16/9 - 2/9
5) Simplify.
14/9
(Decimal form: 1.555556)

We can't really do this without seeing 28, but I can give you an educated guess. The best way for me to proceed is to solve c.
The conjecture is that x = a + b. You should always find that to be true. C is the clincher.
Here's how you do that.
x + c = 180o That's true because all straight lines have 180o. If two angles make up the straight line that means that they are always equal to 180o So x + c = 180o
Now we move to the next step. All triangles also have 180o. That means that a + b + c = 180o
So we have two conditions that equal 180o. Equalities can be equated to one another.
a + b + c = x + c Subtract c from both sides.
a + b = x.
Study what has happened. Put in mathese, the two remote interior angles equal the exterior angle, which is what you are trying to prove.
Summary
a cannot be solved without 28
b you should say that the two remote angles (a and b) will always total x
c The proof is provided for you.
Answer:
3
if a is 1 more than b it can be expressed as so:
a=b+1
b+1=a
b^2+1=a^2
b^2=a^2-1
b=a-1
if b if 1 then a is 2
b+1=a
-a+b=-1
a-b=1
a=2, b=1
a=b+1
a+b=3
1+2=3
