F(-12) if f(x) = 2x + 15
Alenkinab [10]

Answer: f(-12)=-9

Step-by-step explanation:

We have the following function:

f(x)=2x+15

And we have to evaluate it when x=-12, this means we have to substitute x by -12:

f(-12)=2(-12)+15

Solving:

f(-12)=-24+15

Finally:

f(-12)=-9

Which irrational number can be multiplied by - J41 to get a product that equals 1?
andreyandreev [35.5K]

Answer: -√1/✓41

Step-by-step explanation:

Let y be the irrational number that will be multiplied by -√41 to get the product that equals 1.

y × (-√41) = 1

We then solve for y, by dividing through with -√41. This will be:

[y × (-√41)]/-√41 = 1/-√41

y = -1/√41

y = -√1/✓41

The irrational number is negative root one over root forty one.

Vlad1618 [11]

Answer:

The simplest (and most commonly used) area calculations are for squares and rectangles. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area
