Answer:
5x + 2
Step-by-step explanation:
Given
10x² - 11x - 6
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 10 × - 6 = - 60 and sum = - 11
The factors are - 15 and + 4
Use these factors to split the x- term
10x² - 15x + 4x - 6 ( factor the first/second and third/fourth terms )
= 5x(2x - 3) + 2(2x - 3) ← factor out (2x - 3) from each term
= (x - 3)(5x + 2) ← in factored form
Thus 5x + 2 is a factor of 10x² - 11x - 6

Answer:
Step-by-step explanation:
Let x be the total no. of strawberries, Let Sue be "S", Let Jim be "J" and Dan be "D"
S = 2x/7
J = 54+S -> J = 54+(2x/7)
D = 78
J+D = 5x/7
54+(2x/7)+78 = 5x/7
132+2x/7 = 5x/7
132 = (5x/7)-(2x/7)
132 = 3x/7
132*7 = 3x
924/3 = x
x = 308.
Therefore, there were initially 308 strawberries in the basket.
Of which; Sue had two-sevenths: 88, Jim had 142 and Dan had 78
To verify our answer, add these to see if we get 308
S+J+D = 308
88 + 142 + 78 = 308
