How do you factor 7+14
mote1985 [20]

You could factor a 7 out of 7 + 14 to get 7(1 + 2).

This would equal the same thing as 7 + 14, which is 21.

7 * 3 = 21.

21 can be factored like so:

1 * 21 = 21

3 * 7 = 21

What is the complete factorization of x² + 4x-45? OA (X+15X(x - 3) OB. (x-9)(x+5) OC. (x+9XX-5) OD. (x-15)(x+3)​
alexira [117]

Answer:

(x+9)(x-5)

x * x = x^2

9 * x = 9x

5 * x = 5x

9x + 5x = 14x

-5 x 9 = -45

x^2 + 9x + 5x -45

x^2 + 14x - 45

Prove that there exists a unique real number solution to the equation x3 + x2 − 1 = 0 between x = 2/3 and x=1
ziro4ka [17]
Replace each of the x values given to see if they give 0. 

0=(2/3)³+(2/3)²-1 
0=(8/27)+(4/9)-1 
0≠-0.259

0=(1)³+(1)²-1 
0≠1

Therefore, you can see that the solution would have to be between 2/3 and 1.

Hope I helped :)

Given the figure below, how much paper is needed to make the drinking cup to the nearest square inch?
miskamm [114]
To find this, we need to find the Surface area of the lateral surface of the cone (without the circle base). 
LSA _{cone} =  \pi rl
Now we just need to plug what we know into the equation
r=1.5 \\l=4
LSA _{cone} =  \pi (1.5)(4) \\LSA_{cone}= 6\pi
Wither you can keep your answer in pi or take it out of pi, depending on what the requirements are. 
To take it out of pi you need to multiply 6 by pi (remembering to use 3.14 as pi in most cases since that is what is generally accepted on tests and exams). 
6 \pi = 6(3.14)= 18.84
Then rounding to the nearest square inch which would mean that the amount of paper needed is =19in²
