AB - C2 = (x2)(3x + 2) - (x-3)2
AB - C2 = 3x3 + 2x2 - (x2 -6x +9)
AB - C2 = = 3x3 + 2x2 - x2 + 6x - 9
AB - C2 = = 3x3 + x2 + 6x - 9
No because solids can't transmit heat by convection, and convection only works because of hotter and quicker moving molecules have a lower density so they rise to the surface. But in a solid, the molecules can't move relative to each other. They only vibrate :)
DEF= 6 ft^2
A= 1/2*b*h
Plug in what you know.
6= 1/2*4*h
Multiply like terms.
6=2*h
Divide 2 on both sides.
3=h
If the base of ABC= 12
12/4=3
3*3=9
A= 1/2*b*h
A= 1/2*12*9
A= 1/2*84
A= 42
The area of ABC is 42 ft^2
I hope this helps!

Steps
1. Do long division so 16 on out and 3744 on inside
2. Find how many 16s go in 37 only 1 so 16 under 37 add two 0s and and on the outside on the side it's 100.
3. Then u subtract 3700 from 1600 and get 2144
4. Then only one 16 goes in 21 so it's another hundred and then subtract 2144 from 1600 and get 544.
5. Then find how many 16 go into 54 only 3 then add a 0 on the 3 and after subtraction get 480 after that subtract 544 from 480 and get 64
6. four 16 go into 64 and then u get 234 as a answer
