Pls - what is the product?
(2x-1)(x+4)

a- o 2x² - 4
b- o zx²+4
c- 2x? +7x-4
d- o 2x² - 7x-4

C. 2x² + 7x - 4

Step-by-step explanation:

Given:

(2x-1)(x+4)

= 2x * (x+4) + (-1) * (x+4)  ⇒ Distributive property.

= 2x² + 8x - x - 4             ⇒ Combine like terms.

= 2x² + 7x - 4

The answer is option C. 2x² + 7x - 4

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
