A, B and C are matrices such that: A=(2 1), B = and C=(5 6). Given
that AB=C, calculate the values of x and y ?

i) Using a matrix method, solve the pair of simultaneous equations
2x-y=0
x+3y=7​

if he has no friends he cant give them out to his friends

step-by-step explanation:

no friends = cant give anything out

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
