Answer:

Option b: .2x + 17

Step-by-step explanation:

Given that:

= (6x + 5) - (4x-14).

By simplifying

"-" sign before bracket will alter the inner signs

= 6x + 5 - 4x + 14

Adding like terms

= 2x + 17

i hope it will help you!

Can someone please help me with this?

Answer:

e = 29.0 will be the answer.

Step-by-step explanation:

Use the sine rule in the given triangle,

$\frac{EF}{\text{sin}(\angle D)}=\frac{DE}{\text{sin}(\angle F)}=\frac{DF}{\text{sin}(\angle E)}$

$\frac{d}{\text{sin}(35)}=\frac{16}{\text{sin}(30)}=\frac{e}{\text{sin}(115)}$

$d=\frac{16\times \text{sin}(35)}{\text{sin}(30)}$

d = 18.35

$\frac{16}{\text{sin}(30)}=\frac{e}{\text{sin}(115)}$

$e=\frac{16\times \text{sin}(115)}{\text{sin}(30)}$

e = 29.002

e ≈ 29.0

Therefore, e = 29.0 will be the answer.

<u>Answer:</u>

A. (x+5)

<u>Step-by-step explanation:</u>

We are given a quadratic expression $x^2+8x+15$ which we will factorize to see which of the given options is a binomial factor of it.

$x^2+8x+15$

Finding the factors of 15 such that when added, they give a result of 8.

$x^2+3x+5x+15\\\\x(x+3)+5(x+3)\\\\(x+3)(x+5)$

Therefore, we can see that $(x+5)$ is that binomial factor that is present in the given options so option A. (x+5) is the correct answer.
