Hendrick wants to enlarge a photo that is 4 inches wide and 6 inches tall. The enlarged photo keeps the same ratio. How y'all is

zhuklara [117]

Answer:

Step-by-step explanation:

Alright, lets get started.

The original photo size is 4 inches wide and 6 inches tall.

So, the ratio of width and height will be = $\frac{4}{6}=\frac{2}{3}$

The new enlarged photo will be of the same ratio means 2:3

The width of enlarged photo is given as 12 inches.

Suppose new height of enlarged photo is H, so

$\frac{12}{H}=\frac{2}{3}$

Cross multiplying

$2H=36$

Dividing 2 in both sides

$H=18$ inches

So the height of new enlagred photo will be 18 inches. : Answer

Hope it will help :)

F(x) = 2x and g(x) = x + 1, find f(3) and find gf(3)

lord [1]

Answer:

6 and 7

Step-by-step explanation:

To evaluate f(3), substitute x = 3 into f(x) , that is

f(3) = 2(3) = 6

To evaluate g(f(3)), substitute f(3) = 6 into g(x)

g(6) = 6 + 1 = 7
