Answer:
108 degrees inside each corner
Step-by-step explanation:
360/5=72
180-72=108
Answer: I think its b
Step-by-step explanation:
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
X³ - 12x² + 35x
x(x² - 12x + 35)
x(x-5)(x-7)
1,000 = 10^3 (3 because there are 3 digits after the first one)
2,000 = 2 * 10^3
