Answer:
Im on the same question so dont copy word for word
Step-by-step explanation:
The first error he made is that he didn't do the right steps in order to find the area of the two triangles. Instead he should have done 0.5 X 16 X 15 X 2= 240
Then the area for the three rectangles should be 16 X 8 + 17 x 8 + 17 X 8 = 400
If you add it all together, the surface area is actually 640 square meters.
Answer: 18x^3-9x^2+21x
Solution:
3x(6x^2-3x+7)=
Applying the distributive property in the multiplication to eliminate the parentheses:
(3x)(6x^2)+(3x)(-3x)+(3x)(7)=
(3*6)x^(1+2)+3*(-3)x^(1+1)+(3*7)x=
18x^3-9x^2+21x
