When you add up the sum of the digits, it should be a multiple of three. 21 is 2 plus 1 equals 3, so since 3 is a multiple of three, 21 is divisible by 3
Answer i think its 0.5 i searched it and thats what it said
Step-by-step explanation:
In order to Sherman a line that is either parallel or perpendicular to another line, you first have to put the equation into slope intercept form. This means you have to solve for y.
3x+4y = 7
4y = -3x + 7
y = (-3/4)x + (7/4)
The slope of the line is -3/4. Online which is perpendicular would have a slope of 4/3, The negative reciprocal.
Now that you know the slope, you can write many different equations that would be perpendicular to the original.
y = (3/4)x + any y-intercept....Pick a number, any number... 7. ... y=(3/4)x+7
... -2 ...y = (3/4)x - 2. Literally you can pick any number.
Ok since it’s a 45 45 90 right triangle then both sides equal 5. And to find x you do
A^2 +b^2=c^2
5^2 +5^2= c^2
25+25=c^2
50=c^2
Take the square root of both sides and you get X= 5 square root of 2 or 7.071(rounded)
