Solve for each of the following proportions:<br> a. 5/x=30/42<br> b. x/8=-12/32
andreev551 [17]

Answer:

A. x = 7

B. x = -3

Step-by-step explanation:

A.  5/x = 30/42

5/x = 5/7

5 = 5/7 x

5= 5x/7

5 x 7 = 5x

35 = 5x

35/5 = x

7 = x

x = 7

B.  x/8 = -12/32

x/8 = -3/8

x = - 3/8 x 8

x = -  24/8

x = -3

Hope this helps you have a gr8 day :3

If f(x) = 2x2 + 3 and g(x)=x2-7, find (f- g)(x).
Len [333]

The difference of the given functions is x^2 + 10

<h3>Difference of functions</h3>

Given the following functions

f(x) = 2x^2 + 3 and

g(x)=x^2-7

Take the difference

(f-g)(x) = 2x^2 + 3 - (x^2 - 7)

(f-g)(x) = 2x^2 - x^2 +3 + 7

(f-g)(x) = x^2 + 10

Hence the difference of the given functions is x^2 + 10

Mamont248 [21]

Answer:

D. 11.4 miles.

Step-by-step explanation:

Distance between the Center and the Mall = √(5^2 + 3^2) = √34.

Distance between The Park and the Center = √(4^2 + 4^2) = √32.

So the Distance between The Mall and the Park is √34 + √32

=  11.4 miles (answer).
