Answer:
B
Step-by-step explanation:
This quadratic factors.
x^2 - 15x + 56
= (x - 7)(x - 8)
x - 7 = 0
x = 7
=====
x - 8 = 0
x = 8
====
{7,8}
The potential solutions of
are 2 and -8.
<h3>Properties of Logarithms</h3>
From the properties of logarithms, you can rewrite logarithmic expressions.
The main properties are:
- Product Rule for Logarithms -

- Quotient Rule for Logarithms -

- Power Rule for Logarithms -

The exercise asks the potential solutions for
. In this expression you can apply the Product Rule for Logarithms.

Now you should solve the quadratic equation.
Δ=
. Thus, x will be
. Then:

The potential solutions are 2 and -8.

Answer:
=x⁴−x³−14x²
Step-by-step explanation:
<h3>Let's simplify step-by-step.</h3>
x²(3x²+5x−4)−2x²(x²+3x+5)
<h3>Distribute:</h3>
=(x²)(3x²)+(x²)(5x)+(x²)(−4)+−2x⁴+−6x³+−10x²
=3x⁴+5x³+−4x²+−2x⁴+−6x³+−10x²
<h3>Combine Like Terms:</h3>
=3x⁴+5x³+−4x²+−2x⁴+−6x³+−10x²
=(3x⁴+−2x⁴)+(5x³+−6x³)+(−4x²+−10x²)
=x⁴+−x³+−14x²

Answer:
Mean = £1.8 million
Step-by-step explanation:
The MEAN is the sum of all the numbers divided by the number of numbers.
- <u>There are 5 numbers in total</u>
- <u>The sum is
million</u>
Hence the mean is
million
Answer:
x=115 y=65
Step-by-step explanation:
You get 115 for X because angle x is vertical to 115 degrees.
You get 65 because y is supplementary to x, and 180-65=115.
