Answer:
3 - 10x³ - x² - 11x + 6
Step-by-step explanation:
Each term on the upper row is multiplied by each term on the lower row.
This can be expressed as
3x²(x² - 5x + 2) + 2x(x² - 5x + 2) + 3(x² - 5x + 2) ← distribute parenthesis
= 3 - 15x³ + 6x² + 2x³ - 10x² + 4x + 3x² - 15x + 6 ← collect like terms
= 3 - 10x³ - x² - 11x + 6

Answer:
1.60
Step-by-step explanation:
Assuming that this is a cylindrical pipe, the area can be determined by applying the formula for calculating the area of a circle.
i.e Area =
So that,
for the inner part of the pipe,
r =
=
= 2.5 feet
Area of the inner part of the pipe =
= 3.14 x
= 19.625
Are of the inner part of the pipe is 19.63 .
Total diameter of the pipe = 5 + 0.2
= 5.2 feet
r =
= 2.6 feet
Area of the pipe =
= 3.14 x
= 21.2264
Area of the pipe is 21.23 .
Thus the cross sectional area = Area of the pipe - Area of the inner part of the pipe
= 21.2264 - 19.625
= 1.6014
The cross sectional area of the cement pipe is 1.60 .
