T=D/R
You must isolate T so you divide R on both sides. This isolates T and gives you the answer.
The expressions x2 - 14x + 49 and (x - 7)2 are equivalent.
(x + a)^2 = (x + a)(x + a) = x^2 + 2ax + a^2
In this case 2a = -14 so a= -7 and a^2 = 49
Yes
If they form 90 degrees, they are perpendicular
<span>STEP 1: Stick a "y" in for the "f(x)" guy:STEP 2: Switch the x and y. ( because every (x, y) has a (y, x) partner! ):STEP 3: Solve for y:<span>STEP 4: Stick in the inverse notation, continue. 1 2 3.

The middle is a square with side length of 12cm
Area of the square = 12 x 12 = 144 cm^2
There are 4 triangles with base of 13cm and height of 8 cm
Area of triangle = 1/2 x base x height
Area = 1/2 x 12 x 8 = 48cm^2 each
48 x 4 = 192 cm^2
Total area = 144 + 192 = 336 cm^2
