Answer:
21(11 +3x) or simplified more, would be: 231 + 63x
Step-by-step explanation:
P E M D A S
First, Do what is in the parethesis
7 x 3(5 x 2 + 3x + 1)
7 x 3(10 + 1 + 3x)
7 x 3(11 +3x)
Since there are no exponents move on to the next step.
Then multiply.
21(11 + 3x)
I didn't know whether if you were trying to put 5x(2) or not, so it got me confused! Sorry if this isn't right equation! But I hoped this helped!
If simplifies even more, it would be
231 + 63x
(If they wanted it to be in simpilest form)
9514 1404 393
Answer:
0
Step-by-step explanation:
If a=b, you are asking for a whole number c such that ...
c = √(a² +a²) = a√2
If 'a' is a whole number, the only whole numbers that satisfy this equation are ...
c = 0 and a = 0.
0 = 0×√2
The lowest whole number c such that c = √(a²+b²) and a=b=whole number is zero.
__
√2 is irrational, so there cannot be two non-zero whole numbers such that c/a=√2.
_____
<em>Additional comment</em>
If you allow 'a' to be irrational, then you can choose any value of 'c' that you like. Whole numbers begin at 0, so 0 is the lowest possible value of 'c'. If you don't like that one, you can choose c=1, which makes a=(√2)/2 ≈ 0.707, an irrational number. The problem statement here puts no restrictions on the values of 'a' and 'b'.
