Which choice represents the solution for x2 = 676?

A) x =
16
B) x =
676
C) x = ±
16
D) x = ±
676

Step-by-step explanation:

676÷2=338

338÷2=169

169÷13=13

13÷13=1

then 676 = 2²×13² = 26²

then x² = 676 ⇔ x² = 26² ⇔ (x-26)(x+26) = 0 ⇔ x = 26 or x = -26

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632

isocolese triangle

we know that the line connect a and b is the hyptonuse

so first find the hypotonuse length using the distance formula, call the length c

since it is an isocolese triangle, the lengths of the legs are the same

using pythagorean theorem,

in this case, a=b since isocolese triangle so we get

or

we can find c so we can find the distances

we know that if we draw 2 circles, each has center at a and b, and find where they intersect, we can the 2 possible locations for c

if a has center at (xa,ya) and b has center at (xb,yb), then we can solve where

and

intersect to find where they intersect

i'm not going to put an example because i have to go to class. i hope this explanation is enough
