Answer:
30
Step-by-step explanation:
Polynomials are perfect squares when the first term (term x2) and the third term (term 49) are both squares. In order to find the value of b, you must take the square root of the third term and multiply by the exponent in the first term. This means since the sqrt(49) is 7, and 7x2=14; then the correct answer is C. 14.
-- Remember this only works on perfect square polynomials.
Answer: New York
Step-by-step explanation:
Answer:
(5 + 3y)(25 - 15y + 9y²)
Step-by-step explanation:
This is a sum of cubes and factors in general as
a³ + b³ = (a + b)(a² - ab + b²), thus
125 + 27y³
= 5³ + (3y)³ with a = 5 and b = 3y
= (5 + 3y)(5² - 5(3y) + (3y)² )
= (5 + 3y)(25 - 15y + 9y²)
Answer:
D = K-10
Step-by-step explanation:
Let the number of games won by Dave's favourite basketball team be D and Kimiko's be K.
D + 10 = K
therefore,
D = K-10
