Answer:

2784 cm^2

Step-by-step explanation:

I have indicated in the pic there are 4 types of rectangles:

green : 20 x 4 = 80

red : 18 x 4 = 72

yellow : 20 x 18 = 360

blue : 18 x 16 = 288

green has 6 identical surface area so 6 x 80 = 480

red has 4 so 4 x 72 = 288

yellow has 4 so 4 x 360 = 1440

blue has 2 so 2 x 288 = 576

total : 480 + 288 + 1440 + 576 = 2784

If f(x) = -3x - 5 and g(x) = 4x - 2, find (F- g)(x).

yan [13]

Answer:

If f(x) = -3x - 5 and g(x) = 4x - 2 then (f - g)(x) = -7x - 3

Solution:

We need to determine the value of (f - g)(x)

Given that the function is f(x) = -3x - 5 and the other function is g(x) = 4x - 2

The value of (f - g)(x) can be found by as follows:

(f - g)(x) = f(x) - g(x)

On substituting the given value of f(x) and g(x) we get

(f - g)(x) = (-3x - 5) - (4x - 2)

Upon solving we get

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

Hence the value of (f - g)(x) is equal to -7x - 3

If 9% of a number equals 5, find 36% of that number.

lakkis [162]

Answer:

Step-by-step explanation:

You can set this up in an algebraic equation:
.09x=5 which translates to 9% times a variable or unknown number equals 5
Divide both sides by .09 which turns to 55.5
Multiply by .36 to find 36% of that number which equals 20

Hey! Can someone please answer this?

Lelechka [254]

This picture should provide a full answer. What I did was rearrange the equation to get Tan(x) on one side, then in order to get rid of the Tan, I used Arctan, which got us the final answer.

3 and 11 are the only two because 33 only has four factors: 1,3,11,33.
1 - in some cases people say this is prime, but it is now widely considered to not be a prime number
3 - prime
11- prime
33 - not prime, divisible by 3 and 11
