Answer:-4s+14
Step-by-step explanation: combined like terms.
2s-6s= -4s, 4+10=14
Answer:
the answer is -196 im sorry if i got it wrong
Step-by-step explanation:
Answer:
--273
Step-by-step explanation:
100th term is equal a1 + 99d so
100th term = 222 + (-5×99) = -273

f(x) = x² + 14 g(x) = x - 2 -1 ? I think it means evaluate when x = -1
Find (f(x) + g(x)) when x = -1
(f(x) + g(x)) = [ ( x² + 14) + (x - 2)] insert f(x) and g(x)
= [ x² + x + 14 - 2] add like the term
(f(x) + g(x)) = x² + x + 12
(f(-1) + g(-1)) = (-1)² + (-1) + 12 evaluate at x = -1
= 1 - 1 + 12
= 12
Answer:
(x + 7)(2x + 3)
Step-by-step explanation:
Given
2x² + 17x + 21
Consider the factors of the product of the x² term and the constant which sum to give the coefficient of the x- term.
product = 2 × 21 = 42 and sum = + 17
The factors are + 14 and + 3
Use these factors to split the x- term
2x² + 14x + 3x + 21 ( factor the first/second and third/fourth terms )
= 2x(x + 7) + 3(x + 7) ← factor out (x + 7) from each term
= (x + 7)(2x + 3) ← in factored form
