Please help ASAP! Will give BRAINLIEST! Please read the question THEN answer correctly! No guessing.

KIM [24]

Answer:

C. (x + 8) (x + 7)

Step-by-step explanation:

To factor this trinomial, you must split the middle term (15x) into two terms that can be added to get 15x, and multiplied to get 56:

$x^2 + 15x + 56$

$x^2 + 7x + 8x + 56$

Group:

$(x^2 + 7x) (8x + 56)$

Take out the GCF (Greatest Common Factor):

x(x + 7) 8(x + 7)

(x + 8) (x + 7)

Use the echelon method to solve the following system of two equations in two unknowns. Check your answer. x+y=17 amd 9x-y=73

Komok [63]

Answer:

y = 8

x = 9

Step-by-step explanation:

given equation,

x + y = 17 ........(1)

9 x - y = 73...........(2)

writing in matrix form

A X = B

$\begin{bmatrix}1 &1 \\ 9 &-1 \end{bmatrix} \begin{bmatrix}x\\ y\end{bmatrix}=\begin{bmatrix}17\\73 \end{bmatrix}$

using augamented matrix A|B

$\begin{bmatrix}1 &1& 17\\ 9 & -1 & 73\end{bmatrix}$

using row transformation

R₂ = R₂ - 9 R₁

$\begin{bmatrix}1 &1& 17\\ 0 & -10 & -80\end{bmatrix}$

now,

$\begin{bmatrix}1 &1 \\ 0 &-10 \end{bmatrix} \begin{bmatrix}x\\ y\end{bmatrix}=\begin{bmatrix}17\\-80 \end{bmatrix}$

now

-10 y = -80

y = 8

and

x + y = 17

x = 17 -8

x =9
