Answer:
I agree with Helen because she is right that the volume is about 175 cubic inch. and it is a triangular prism.
Step-by-step explanation:
Answer:
= 12x³ - 6x² - 7
Step-by-step explanation:
Differentiate each term using the power rule
(a
) = na
Given
y = 3
- 2x³ - 7x + 5, then
= 4.3
- 3.2
- 7
+ 0
= 12x³ - 6x² - 7
The formula for perimeter is 2L +2W
Replace w with 20 and L with 11:
2(11) + 2(20) = 22 + 40 = 62
This does not equal 64, so the perimeter cannot be 64 with 20 and 11 being the dimensions.
(First equation:Multiply 6•7=42. 42+5=47)=(second equation:7 to the 2nd power is 49. 49-2=47 )
