Hello from MrBillDoesMath!

Answer:

4x^4 - 2x^3 + 4x^2 -2x + ( +\-7 + 1)

See Discussion for meaning of "+\-" symbol above

Discussion:

** The first polynomial (10x^4-2x 7)    is missing an operand between 2x and 7. I have indicated it below by using (+\_), meaning I don't know what you wanted.**

(10x^4-2x +\- 7)-(6x^4+2x^3-4x^2-1)      => combine like terms

(10x^4 - 6x^4) - (2x^3) - (-4x^2) + (-2x) + ( +\-7 +1) =

4x^4 - 2x^3 + 4x^2 -2x + ( +\-7 + 1)

Thank you,

MrB

Please do my all question​
Kryger [21]

The factorization of the numbers is obtained as

(a) 36 = 2² x 3²,

(b) 60 = 2² x 3 x 5,

(c) 84 = 2² x 3 x 7,

(d) 99 = 3² x 11 and

(d) 180 = 2² x 3² x 5

<h3>Factor of the numbers</h3>

To factorize the numbers we use their factors as show below;

<h3>Factors of 36</h3>

36 = 2² x 3²

<h3>Factors of 60</h3>

60 = 2² x 3 x 5

<h3>Factors of 84</h3>

84 = 2² x 3 x 7

<h3>Factors of 99</h3>

99 = 3² x 11

<h3>Factors of 180</h3>

180 = 2² x 3² x 5

Thus, the factorization of the numbers is obtained as 36 = 2² x 3², 60 = 2² x 3 x 5, 84 = 2² x 3 x 7, 99 = 3² x 11 and 180 = 2² x 3² x 5.

Find the volume of the cylinder in terms of pi h = 6 in. and r = 3 in. A 54π in.3 B108π in.3 C324π in.3 D 27π in.3
Orlov [11]

Answer:

Option A. 54\pi\ in^{3}

Step-by-step explanation:

we know that

The volume of the cylinder is equal

V=\pi r^{2}h

where

r is the radius of the base of cylinder

h is the height of the cylinder

we have

r=3\ in

h=6\ in

substitute

V=\pi (3)^{2}(6)

V=54\pi\ in^{3}
