Answer:
[ 4 2 ] x [ -2 5 7 -1 ] = [- 10,836]
Step-by-step explanation:
Here, the given expression is:
[ 4 2 ] x [ -2 5 7 -1 ]
Now solving : [ -2 5 7 -1 ] , we get
[ -2 5 7 -1 ] = [-258]
Now simplifying
[-258] x [ 4 2 ] = - 10,836
⇒ [ 4 2 ] x [ -2 5 7 -1 ] = [- 10,836]
Hence the solution is: [- 10,836]

Answer:
(4, -10), (4, 6)
Step-by-step explanation:
The vertical diameter is on the vertical line through the center of the circle. That line is x=4.
The square of the radius is 64, so the radius is √64 = 8. The y-coordinate of the diameter end points will be the y-coordinate of the center ±8.
So, the points of interest are ...
(4, -2±8) = (4, -10) and (4, 6) . . . . end points of the vertical diameter
X= base
one side= x-6
other side= 4+x
x+x-6+4+x = 43
3x=43+2
x=15 length of base
