The matrices are
S =(4 11 T= ( -8 11
-3 -8) 3 4 )
Inverse of a matrix is a matrix derived from another matrix such that if you pre- multiply it with the original matrix you get a unit matrix.
if we multiply S and T
ST will be
( 4 11 × (-8 11 = ( 1 0
-3 -8) -3 -4) 0 1)
and also TS
( -8 11 × (4 11 = ( 1 0
-3 -4) -3 -8) 0 1)
therefore, matrices S and T are inverses of each other because ST = TS= I

Hope this helps :D
(Sometimes i don’t know what the question is asking so pls tell me if I’m wrong)
A = b+5
ab = 3300
(b+5)b = 3300
b² +5b -3300 = 0 (quadratic formula)
b=55
a=60 (by first relation)
Answer:
16 sq. units
Step-by-step explanation:
<u>The formula for the area of a triangle:</u>
<u>If base and height are known as:</u>
- b = 8 units and h = 4 units
<u>Then the area is:</u>
- A = 1/2*8*4 = 16 sq. units
