Monica retiled her square kitchen for $338. If the company she used charged $2 per square foot, how wide is her kitchen?

Response:

15

Step-by-step explanation:

To determine the number of classes, subtract 10 from 146 which leaves you with 136. Dividing 136 by 9 results in approximately 15.1 repeating, but since classes cannot be a fraction, the answer rounds down to 15.

Solution:

We know, g(x) = f(x) + k --------(1)

It is given that f(x) = (x+2)

and g(x) = (x+5)

Substituting f(x) and g(x) into equation (1):

→ (x+5) = (x+2) + k

→ = k

→ k =

Thus, the value of k is 1.

(4 – 2i)(6 + 2i)

Use FOIL

First: 4 multiplied by 6 equals 24

Outer: 4 times 2i gives 8i

Inner: -2i times 6 results in -12i

Last: -2i times 2i equals -4i², which simplifies to 4

Combine the results

24 + 8i - 12i + 4

Final result: 28 - 4i

The answer is: 28 - 4i
