Let p = 0
1 0
and = 0
0 0

a. give an example of a 2 × 2 matrix a, not with al entries equal to zero, such that pp=
b. give an example of a 2 × 2 matrix b with pp≠
c. give an example of a 2 × 2 matrix c such that cc = for al 2 × 2 matrices
d. if a 2 × 2 matrix has the property that + = for al 2 × 2 matrices must be the zero
matrix explain.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

correct answer is c. just did it
