Which polynomial represents the difference below? (8x^2+9)-(6x^2+2x+2)

grin007 [14]

Answer:

The polynomial is 2 x² - 2x + 7

Step-by-step explanation:

Given polynomial

(8 x² + 9 ) - (6x² +2x +2)

= 8 x² +9 - 6x² - 2x -2

= 8x² - 6x² - 2x + 9-2

= 2 x² - 2x + 7

The polynomial is 2 x² - 2x + 7

COLLEGE PREP In the diagram, mLAGC = 38°, m/CGD=71°, and m/FGC = 147 °. Which of the following

Cerrena [4.2K]

The statements that are true are:

A. m<AGB = 19°

D. <BGD is a right angle

<h3>What is a Right Angle?</h3>

A right angle is an angle that measures 90 degrees.

Given the diagram, where:

m<AGC = 38°,

m<CGD = 71°,

m<FGC = 147°

We have the following measures:

1/2(m<AGC) = m<AGB

1/2(38) = 19°

m<CGD + m<AGC = m<BGD

Substitute

71 + 19 = m<BGD

90 = m<BGD

m<BGD = 90° [this is a right angle].

Therefore, the statements that are true are:

A. m<AGB = 19°

D. <BGD is a right angle

Answer:

Part A) The volume of the entire cone is $168\pi\ in^3$

Part B) see the explanation

Step-by-step explanation:

Part A) we know that

The volume of a cone is equal to

$V=\frac{1}{3}\pi r^{2}h$

where

r is the radius of the base of the cone

h is the height of the cone

In this problem triangle ABD is similar to triangle ACE

Remember that If two figures are similar, then the ratio of its corresponding sides is proportional

$\frac{AB}{AC}=\frac{BD}{CE}$

substitute the given values

$\frac{7}{14}=\frac{3}{x}$

solve for x

$x=14(3)/7\\x=6\ in$

To find out the volume of the entire cone we have

$r=CE=x=6\ in$

$h=AC=14\ in$

substitute in the formula

$V=\frac{1}{3}\pi (6)^{2}(14)$

$V=168\pi\ in^3$

Part B) How did you determine the value for x in triangle ACE

In this problem triangle ABD is similar to triangle ACE

If two figures are similar, then the ratio of its corresponding sides is proportional and its corresponding angles are congruent

$\frac{AB}{AC}=\frac{BD}{CE}$

substitute the given values and solve for x
