Answer:
−2x4−18x3y
Step-by-step explanation:
Let's simplify step-by-step.
(−3x2)(xy+2x2)+7x4−3x3(5y+x)
Distribute:
=(−3x2)(xy)+(−3x2)(2x2)+7x4+−3x4+−15x3y
=−3x3y+−6x4+7x4+−3x4+−15x3y
Combine Like Terms:
=−3x3y+−6x4+7x4+−3x4+−15x3y
=(−6x4+7x4+−3x4)+(−3x3y+−15x3y)
=−2x4+−18x3y
The surface area is all the areas of all the exterior faces in a 3D shape.
Doing all the possibilities, 4 * 5 * 2 , 5 * 7 * 2, 4 * 7 * 2 = total surface area
40 + 70 + 56 = 166 m^2
The answer is 2. 166 m^2
Final answer: 5
Step by step process:
You can make the equation a little simpler by putting in the 3 for x
btw I show exponents with this ^
(3)^2/3 + 2
3^2=3*3=9
Now you have 9/3 + 2 and you keep simplifying
9/3=3
3+2=5
Final answer: 5
