Answer:
(ab - 6)(2ab + 5)
Step-by-step explanation:
Assuming you require the expression factorised.
2a²b² - 7ab - 30
Consider the factors of the product of the coefficient of the a²b² term and the constant term which sum to give the coefficient of the ab- term
product = 2 × - 30 = - 60 and sum = - 7
The factors are - 12 and + 5
Use these factors to split the ab- term
= 2a²b² - 12ab + 5ab - 30 ( factor the first/second and third/fourth terms )
= 2ab(ab - 6) + 5(ab - 6) ← factor out (ab - 6) from each term
= (ab - 6)(2ab + 5) ← in factored form
Answer:
Hey!
The car travelled 135 kilometers!
Step-by-step explanation:
Here you have to do the speed (45km/h) multiplied by the time (3 hours)
45 x 3 = 135
So the car has travelled 135 kilometers!

Answer:
A function that is one to one
Step-by-step explanation:
Each input has one output.
Answer:
h(f(x)) = 2x - 11
(the second answer is f(h(x)) = 2x - 4)
Step-by-step explanation:
h(x-7) = 2(x-7) + 3
h(x) = 2x -14 + 3
h(x) = 2x - 11
The answer A shows the integers from greatest to least
