Flauer [41]

Hi,

Equation:

$- 7 \times (- 5)$

Multiplying two negatives equals a positive.

$( - ) \times ( - ) = ( + )$

Now equation looks like:

$7 \times 5 = 35$

Hope this helps.

The mean of four consecutive even numbers is 15. The greatest of these numbers is a1. The least of these numbers is a2.

skad [1K]

X + (x + 2) + ( x + 4) + (x + 6)
-----------------------------------   = 15
   4

4x + 12
--------- = 15
    4

Multiply by 4 on both sides

4x + 12 = 60
subtract 12 from both sides
4x = 48
divide by 4 on each side
x = 12
x + 2 = 14
x + 4 = 16
x + 6 = 18

Given f(x) = x^2 + x − 2 and g(x) = 2x − 4, identify (f + g)(x).

shutvik [7]

Answer:

(f + g)(x) = x^2 + 3x - 6

Step-by-step explanation:

Given f(x) = x^2 + x − 2 and g(x) = 2x − 4

Plug in:

(f + g)(x) = x^2 + x − 2 + 2x − 4

(f + g)(x) = x^2 + 3x - 6
