Step-by-step explanation:
Answer:
(x + 3)(2x + 5)
Step-by-step explanation:
Given
2x² + 11x + 15
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 = 2 × 15 = 30 and sum = + 11
The factors are + 6 and + 5
Use these factors to split the x- term
2x² + 6x + 5x + 15 ( factor the first/second and third/fourth terms )
= 2x(x + 3) + 5(x + 3) ← factor out (x + 3) from each term
= (x + 3)(2x + 5)

Answer:
Total weights for the orange and pineapple = 145 + 1015 = 1160 grams.
Step-by-step explanation:
Let the weight of pineapple be x grams and weight of orange by y grams.
Now, weight of a pineapple = 7 (weight of an orange)
∴ x = 7y
Also, x = y + 870 (∵ pineapple weighs 870 more than pineapple)
Substituting the value of x in above equation,
7y = y + 870
7y - y = 870
6y = 870
y = 870/6 = 145
Weight of an orange = 145 grams
Weight of pineapple = 7 × 145 = 1015 grams
Total weights for the orange and pineapple = 145 + 1015 = 1160 grams.
