So we can use the Pythagorean's Theorem to figure this out.
The Pythagorean's Theorem is: a^2 + b^2 = c^2
Basically, leg1 squared plus leg2 squared = hypotenuse squared
So the two legs are 12 and 16, so we can put them in the equation.
12^2 + 16 ^ 2 = hypotenuse ^2
Or,
144 + 256 = hypotenuse ^ 2
400 = hypotenuse ^ 2
Then we can do the square root of 400 to find the hypotenuse.
√400 = 20
The length of the hypotenuse is 20 centimeters.
First square both sides
1-3x=(x+3)^2 use foil to unfactor it
1-3x=x^2+6x+9 subtract 1 from both sides
-3x=x^2+6x+8 add 3x to both sides
0=x^2+9x+8
Now that we got it equal to zero you have to factor the new trinomial
0=(x+1)(x+8)
Now since both are being multiplied by each other, if you get 1 of them to equal zero then both equal zero since 0 times anything equals 0.
So your solutions are x=-8 and x=-1

Step-by-step explanation:
28/ 7 = 4 28 1/7 = 28/7 then u will have to divide 7 28 = 4 28 7/1 = cant get even number
