Answer:
Energy may be released.
Rock can bend and break.
Forces affect Earth's rocks.
Modeling the above problem in matrix form we have,
[3 5;9 7]*[x y]'=[49 77]'
AX=b
X=inv(A)*b
X=[1.7500 8.7500]'
ie x=1.7500 and y=8.7500
The way you wrote it, it should be b=3v/hr
Answer: It want let me put the answer in
Step-by-step explanation:
The height is 14 cm.
A=bh/2
42=6h/2
42(2/6)=h
(42÷6)x2=h
7x2=h
h=14
