Answer:

about 4650 square inches

Step-by-step explanation:

The area is the product of length and width. Each conversion factor cancels a unit we don't want and replaces it with a unit we do want.

(1.5 m)(2 m)((1 in)/(0.0254 m))^2 = 3/.00064516 in^2 = 4650.0093... in^2

≈ 4650 in^2

The photograph has an area of 4650 square inches.

If f(x)=4x^2 and g(x)=x+1, find (fog)(x)

iren [92.7K]

Answer: The value of $(f_\circ g)(x)$ is $4(x+1)^2$ .

Step-by-step explanation:

Given: $f(x) = 4x^2 \text { and } g(x) = x+1$

To find: $(f_\circ g)(x)$

As we know it is composition function which means that g(x) function is in f(x) function.

So we have

$(f_\circ g) (x) = f[g(x)]$

$\Rightarrow( f_\circ g)(x)= f(g(x)) = 4(g(x))^2$

Now substitute the value of g(x) we get

$(f_\circ g)(x)= 4(x+1)^2$

Hence, the value of $(f_\circ g)(x)$ is $4(x+1)^2$ .

4-2(x+7)=3(x+5) can ya'll help me with the steps.

maria [59]

Answer:

x = -5

Step-by-step explanation:

4-2(x+7)=3(x+5)

Distribute

4 -2x-14 = 3x+15

Combine like terms

-2x-10 = 3x+15

Add 2x to each side

-2x-10+2x= 3x+15+2x

-10 = 5x+15

Subtract 15 from each side

-10-15 = 5x+15

-25 = 5x

Divide by 5

-25/5 = 5x/5

-5 =x
