Answer:
Step-by-step explanation:
The system of equations is:
● 3x + 2y = 7 
● 2x + 4y = 8 
Where x is the price of a single coffee and y is the price of a single coffee
We will solve this simultaneous equations using the graphing method: 
The solutions is the intersection point of to the lines.
(Picture below)
The intersection point is (1.5,1.25)

Answer:
(x +1) (x + 5)
Step-by-step explanation:
Factorization of x²+6x+5
To factorise this quadratic expression we'll find 2  factors of 5 that when added gives the coefficient of x which is 
Factors = +1 and +5 
Sum = +6, product = +5
Rewriting equation 
x² + x + 5x + 5 
Factorising
x ( x +1) +5 ( x + 1)
(x +1) (x + 5)

Answer:
6x^2  − 10x − 24
Step-by-step explanation:
2(3x + 4)(x - 3)
(6x + 8)( x − 3)
6x^2  − 18x + 8x − 24
6x^2  − 10x − 24
