Answer:
(2x + 4) ( x +1 ) are factors .
Step-by-step explanation:
Given : 2x² + 9x + 4.
To find : Factor.
Solution : We have given that 2x² + 9x + 4.
On factoring 2x² + 8x + 1x + 4.
Taking common 2x from first two terms and 1 from last two terms .
2x ( x +4 ) +1 (x +4 ).
On grouping
(2x + 4) ( x +1 ).
Therefore , (2x + 4) ( x +1 ) are factors .
The factored form of the polynomial 2x² + 9x + 4 is (2x + 1)(x + 4).
Hence the correct answer is 3rd.
Given is a polynomial 2x² + 9x + 4, we need to factorize it.
To factorize the polynomial 2x² + 9x + 4, we can use the factoring method.
Step 1: Multiply the coefficient of the quadratic term (2) with the constant term (4). In this case, 2 × 4 = 8.
Step 2: Find two numbers that multiply to give 8 and add up to the coefficient of the linear term (9).
In this case, the numbers are 1 and 8 because 1 × 8 = 8 and 1 + 8 = 9.
Step 3: Rewrite the middle term (9x) using the two numbers found in step 2. This will split the middle term into two parts.
2x² + 1x + 8x + 4
Step 4: Group the terms in pairs and factor out the greatest common factor from each pair.
(2x² + 1x) + (8x + 4)
Step 5: Factor out the greatest common factor from each pair.
x(2x + 1) + 4(2x + 1)
Step 6: Notice that we now have a common binomial factor, (2x + 1). Factor out this common binomial.
(2x + 1)(x + 4)
Therefore, the factored form of the polynomial 2x² + 9x + 4 is (2x + 1)(x + 4).
Hence the correct answer is 3rd.

Answer:
y = - 7x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 7x + 2 ← is in slope- intercept form
with slope m = - 7
Parallel lines have equal slopes, thus
y = - 7x + c ← is the partial equation
To find c substitute (- 5, 32) into the partial equation
32 = 35 + c ⇒ c = 32 - 35 = - 3
y = - 7x - 3 ← equation of parallel line
