G(x)= -8x-3, evaluate g(x)+g(2)
makkiz [27]

Answer:

-8x - 22

Step-by-step explanation:

Step 1: Define

g(x) = -8x - 3

g(2) is x = 2

Step 2: Find g(2)

g(2) = -8(2) - 3

g(2) = -16 - 3

g(2) = -19

Step 3: Find g(x) + g(2)

-8x - 3 + -19

-8x - 3 - 19

-8x - 22

Expand, answer should be a polynomial in standard form<br><br> (5a+2)(a+4)=
castortr0y [4]

Answer:

The standard form of the expression (5a+2)(a+4) is 5a^{2}  + 22 a + 8.

Step-by-step explanation:

Here, the given expression is (5a+2)(a+4).

Now, (5a+2)(a+4) = 5a(a+4) + 2(a+4)

= 5a^{2}  + 20 a + 2a + 8

=  5a^{2}  + 22 a + 8

or,  (5a+2)(a+4) = 5a^{2}  + 22 a + 8

Also,  Standard Quadratic form is ax^{2}  +  bx + c = 0

Hence, the standard form of (5a+2)(a+4) is 5a^{2}  + 22 a + 8.
