2. a cube is made up of six congruent square faces. find the length of the inner diagonal of the cube. note that is the hypotenuse of right triangle adh. (round your answer to the nearest hundredth.)

a) use the 45-45-90 property or the pythagorean theorem to find the length of the diagonal (dh) of the bottom base of the cube.
b) use the length from part a as one leg, the length of side ad, and the pythagorean theorem to find the length of the diagonal ah.

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
