You can use the pythagorean theorem for this. a^2 + b^2 = c^2 1) 6^2 + 3^2 = ? 2) 36 + 9 = 45 3√5 cm of the hypotenuse 4) 6 + 3 + 3√5 = 9 + 3√5

x -2 -2y= 3 x -5 = 2y y = x/2 -5/2 The slope is 1/2, so the perpendicular slope to it would be -2. For me, I find it easier to draw a graph. Find point (-2, -5) and draw a line with slope of -2. Once you hit the y-axis, the number on the axis is you're
The reason why you multiply the fraction by 100 is because the fraction less than one whole number. 2/3 means two thirds of a pie or a pizza. It's only partial of one pie. 1/1, 2/2, 5/5 is 100%. 3/2 is more than one whole number because 2/2 is equal to
1) x = 4y - 1 2) x + 1 = 4y 3) (x + 1) / 4 = y
If you need it to be factored out, then 3a^3 + 12a^2 - 63a (That's how I'm going to write it out) can be divided out by 3a, so it turns out 3a(a^2 + 4a - 21). Next, you can further factor this out into two binomial groups using the reverse method of
