16.30 and 16.3 equal. If you ever have a problem like that then you just add on a zero.
Example:
19.4500 = 19.45 Just add two zeros on the end
19.45 + two zeros = 1.4500
Please: Use "^" to denote exponentiation: <span>2x^2 + 8x - 12 = 0
Reduce this by div. every term by 2: </span><span>x^2 + 4x - 6 = 0
Here a=1, b=4 and c = -6. Square half of b, obtaining (4/2)^2 = 4, and add, and then subtract, this 4 to x^2 + 4x - 6:
</span> x^2 + 4x +4 - 4 - 6 = 0. Rewrite the square as (x+2)^2, obtaining new equation
(x+2)^2 = 10. Take the sqrt of both sides: x+2 = plus or minus sqrt(10).
Finally, solve for x: x = -2 plus or minus sqrt(10).
To get the answer type 2•4•3+2•4•2+2•3•2
in to a calculator And you’ll get “52m”
Answer: 4 2^ + 5

Answer: m1 m2 and m5 all equal to 135 as well
While m3 m6 and m4 are 45
Why: since they are on a line the two angles together should equal 180. So 180- 135= 45
