 Your equation is 1/5 + 1/3 =1/x To solve you have to find the common denominator which is 15 So (1/5)3 and (1/3)5

                                          = 3/15+5/15=8/15

                                                  8/15=1/x now cross multiply

                                                   =15/8

This is the answer I got.

PLEASE HELP!!!!! Consider the functions f(x)=x−7 and g(x)=4x3.<br> What is f(x)+g(x)?
Karolina [17]

Answer:

The answer is 13x-7

Step-by-step explanation:

f(x) is x-7, and g(x) is 4x3. 4x3 can also mean 12x , because 4x3 is 4*x*3. So, f(x) can be replaced with x-7, and g(x) can be replaced by 12x. (x-7)+(12x) is 13x-7.

The area of the given trapezoid is 38 in².

<h3>What is a trapezoid?</h3>

A trapezoid is a quadrilateral (has four sides and four angles) with a single pair of parallel sides. The area (A) of a trapezoid is given by:

A = (1/2) * (a + b) * h

Where a, b are the parallel sides and h is the height of the trapezoid.

Given that a = 8, b = 11, h = 4, hence:

A = (1/2) * (8 + 11) * 4 = 38 in²

The area of the given trapezoid is 38 in².

Please answer this correctly
Stolb23 [73]

Answer:

502.4 square inches

Step-by-step explanation:

To find the area of the shaded region, you first need to find the area of the smaller circle with diameter 12, and then subtract that from the area of the larger circle. Since the diameter of a circle is twice the radius, the radius of the smaller circle is 6, and its area is therefore:

\pi \cdot 6^2 = 3.14\cdot 36=113.04

The area of the larger circle, which has radius 6+8=14, is:

\pi \cdot 14^2= 3.14 \cdot 196=615.44

Subtracting the area of the smaller circle from his, you get an area of 502.4 square inches for the shaded area. Hope this helps!
