Answer:

x = 29

Step-by-step explanation:

(x + 3)/4 = 8

Multiply both sides by 4.

x + 3 = 8 × 4

x + 3 = 32

Subtract both sides by 3.

x = 32 - 3

x = 29

A square sheet of paper measures 42 centimeters on each side. What is the length of the diagonal of this paper?

Illusion [34]

59.4cm
Use Pythagorean theorem to find the diagonal (^ means exponent)
a^2 + b^2 = c^2
42^2 + 42^2= c^2
1764+1764=c^2
3528=c^2
square root both sides
c= 59.39696962
round and you get 59.4 cm

Given f ( x ) = 1 x + 10 , find the average rate of change of f ( x ) on the interval [ 8 , 8 + h ] . Your answer will be an exp

son4ous [18]

Answer: 1

Step-by-step explanation:

$f(8+h)=8+h+10=18+h\\\\f(8)=8+10=18$

So, the average rate of change is:

$\frac{(18+h)-18}{(8+h)-8}=\frac{h}{h}=\boxed{1}$

The question is wrong, the expression will not be in terms of h since it is a linear function.
