Answer:

20x^3-14x^2+37x-7

Explanation: We need to simplify the given expression:

(4x^2-2x+7)(5x-1)

Simplification step by step:

4x^2(5x-1)-2x(5x-1)+7(5x-1)4x^2\times5x-4x^2-2x\times5x+2x+7\times5x-720x^3-4x^2-10x^2+2x+35x-7=20x^3-14x^2+37x-7

Therefore this is the simplified expression:

If g(x) = 2x2 + 6x + 5, use synthetic division to find g(-5).
diamong [38]
<h3>Answer:  25</h3>

=================================================

Explanation:

Check out the image below. I've posted the synthetic division table. The value at the very end of the bottom row is the remainder. By the remainder theorem, this is exactly the value of g(-5).

Recall the remainder theorem says: If you divide p(x) by (x-k), then the remainder is p(k). In this case, k = -5 is our test root which is the value placed in the box on the left.

As a way to check the answer, we can say

g(x) = 2x^2 + 6x + 5

g(-5) = 2(-5)^2 + 6(-5) + 5

g(-5) = 25

So the answer is confirmed.

A circle's circumference is approximately 44 cm.
Sav [38]
<h3>Answers</h3><h3>diameter = 14</h3><h3>radius = 7</h3><h3>area = 154</h3>

these are all approximate

======================================

Explanation:

C = pi*d is the formula for the circumference. We know that C = 44 approximately, so,

C = pi*d

d = C/pi

d = 44/3.14

d = 14.01 approximately

d = 14 also approximate

take half of this to get the radius

r = d/2 = 14/2 = 7

Then use this radius to find the circle's area

A = pi*r^2

A = 3.14*7^2

A = 153.86

A = 154  rounding to the nearest whole number

How do defined terms and undefined terms relate to each other ?
dalvyx [7]
<span>In geometry, definitions are formed using known words or terms to describe a new word. There are three words in geometry that are not formally defined. These three undefined terms are point, line and plane. Undefined terms have not been defined, and defined are answered. They are terms that have a relationship with the point od discussion. :)</span>

What is the slope of a line that is parallel to the line y=3/4x+2
stepladder [879]
If two lines are parallel to one another, then their slopes are identical.  The slope in the line above is 3/4.  Therefore, a line parallel to that line will also have a slope of 3/4, it will just have a different y-intercept.
