4*4= 16 + 16= 32 :) You could do 4 * 4 that equals 16 then add 16 to that to get over 28.
H=(√3)*a/2 = 41.2
So, a=2*41.2/√3=47.6
Since the square root of 64 is 8, 8 has an absolute value, so it can be opposites as it, eg. 8 = -8.
Answer: B (2,1)
You know what y is (x-1) so you substitute that for y in the other equation.
3x+ ((4)(x-1))=10
3x+4x-4=10
7x=14
x=2
Then put x=2 into y=x-1
y=2-1
y=1
