What is x2+2x-8=0 by factoring ?

Mathematics
1 answer:
Vaselesa [24]4 years ago
7 0

Answer:

(x+4)(x-2)

Step-by-step explanation:

We need to find two numbers that multiply to -8 and add up to 2. These are 4,-2.

Rewrite the polynomial:

x^2-2x+4x-8

and factor each pair:

x(x-2)+4(x-2) = (x+4)(x-2)

It is always desirable to have a higher compounding frequency, regardless of the initial investment or the time horizon. True or
Kruka [31]

Answer:

The provided statement is TRUE.

Step-by-step explanation:

Compounding frequency is the frequency of the interest that is paid in a year.

Higher compounding frequency will return a higher future value along with the constant investment amount and time. Therefore for investment drives higher compounding frequency is favored.

A higher compounding frequency for an investment with the same original investment and time horizon would return additional interest and profit when compared to an investment with a lower compounding frequency.

Thus, the provided statement is TRUE.

Find x Round to the nearest tenth
nikdorinn [45]

Answer:

15.5

Step-by-step explanation:

So the formula here is the square of the tangent length is equal to the product of the exterior part of the secant line and total length of the secant.

So that means we have x^2=10(14+10).

After simplifying the right hand side we have the equation is x^2=10(24) or x^2=240.

To get rid of the square on the x, we square root both sides.

x=sqrt(240)

x=15.49193338

To the nearest tenths, the answer is x=15.5

So 15.5 inches is the length of x.

Write each line in slope-intercept form. Then
Ivahew [28]

Answer:

equation: y = -4x + 7

slope: -4

y-intercept: 7

Step-by-step explanation:

in order to make this equation into slope-intercept form, you have to isolate the y

to do that, you can subtract the 4x on both sides, which will leave y by itself

4x + y = 7

-4x        -4x

y = -4x + 7

the slope is -4

and the y-intercept is 7
