2(2x^2-2x+5) and 2(40x^2-5x+4)
Step-by-step explanation:
Answer:
4x^2−4x+10 = 2(2x^2−2x+5)
2x^2+5x-82x^2+5x−8 = 2(−40x^2+5x−4)
Step-by-step explanation:
4x^2−4x+10
Factor 4x^2−4x+10
4x^2−4x+10
=2(2x^2−2x+5)
2x^2+5x-82x^2+5x−8
Factor 2x^2+5x−82x^2+5x−8
−80x^2+10x−8
=2(−40x^2+5x−4)

How many sheets of plywood would you need for two gables in a home if the gables are 42’ wide by 5’ high?
Answer:
7 sheets
Step-by-step explanation:
Dimension of gabble = 42' by 5'
Dimension of standard plywood sheet : 4' by 8'
Area that will be covered by gabble :
Length * width :
42 * 5 = 210 in²
Area covered by 1 plywood sheet :
4 * 8 = 32 in²
Number of plywood sheets required :
Area of gabble / Area of 1 plywood sheet
210 in² / 32 in²
= 6.5625
This means the number of plywood sheets that will be required is 7

A news reporter states that a study shows that 63% of people prefer vanilla ice cream to chocolate ice cream, plus or minus 2% points. The margin of error in this example is _____.
Answer: 21
Why: 21/2321
Using the concept of a confidence interval, it is that the margin of error in this example is of 2%.
------------------------
A confidence interval for a percentage is written in the following format:
[tex]P \pm M[/tex]
That is, the percentage is of P, plus of minus M points, in which M is the margin of error.

In this question, the percentage is 63% plus or minus 2%, thus, the margin of error is of 2%.A similar problem is given at https://brainly.com/question/21496409
According to the triangle inequity if 20 and 25 are the lengths of two sides of a triangle then an inequality that represents all possible lengths for the third side is_____
A. 0
B. 0
C. 5_
D. 5
Answer and explanation:
The inequality theorem states that the sum of the length of two sides of a triangle is greater than the third side of a triangle.
Also the difference of two sides of a triangle is less than the third side
If we apply this theorem here,
Then we say the third side x<20+25 and x>25-20
Therefore x<45 but >5
5<x<45
Possible sides of x include: 6,7,8,9,10,11,12,13,14,15,16,17,18...not equal to 45 or more than
