Option c
Step-by-step explanation:
First multiply matrix A by -7.
Then multiply the matrix B by -6.
When multiplying a matrix by a number x you must multiply each element of the matrix by x.

Answer:
x=+/-3
Step-by-step explanation:
x^4-5x^2-36=0
factor
(x^2-9)(x^2+4)=0
split into 2 equations because one of these terms will need to equal zero for the eqation to be true
x^2-9=0 x^2+4=0
x^2=9 x^2=-4
x=+/-3 no real numbers
Answer:
56
Step-by-step explanation:
Zoe and Hannah shared tips in the ratio
3:7
Last week Zoe received $24
Hence the amount received by Hannah can be calculated as follows
3/7= 24/x
168= 3x
x= 168/3
= 56
Hence Hannah received €56
