" Given f (x) = 3x + 2 and g(x) = 4 – 5x, find (f + g)(x), (f – g)(x), (f × g)(x), and (f / g)(x).1. = [3x + 2] + [4 – 5x] = 3x + 2 + 4 – 5x. = 3x – 5x + 2 + 4. = –2x + 6. (f – g)(x) 2. = f (x) – g(x)= [3x + 2] – [4 – 5x] = 3x + 2 – 4 + 5x. = 3x + 5x + 2 – 4. = 8x– 2. 3. ...= (3x + 2)(4 – 5x) = 12x + 8 – 15x2 – 10x. = –15x2 + 2x + 8. " - Google

Stuff mart sells ice cream toppings in two different packages. Package one has eight blueberry toppings for $22. Package two has
Leya [2.2K]

Answer:

the cost of the blueberry packing be $2.75 and the cost of the strawberry topping be $1.57

Step-by-step explanation:

The computation is shown below:

Let us assume the blueberry topping be x

And, the strawberry topping be y

Now as per the question

8x = $22

Divide by 2 to the both sides

4x = $11

x = $11 ÷ 4

= $2.75

And,

4x + 7y = $22

Now put the x value in the above equation

4 × (11 ÷ 4) + 7y = $22

11 + 7y = $22

7y = $22 - $11

7y = $11

y = $11 ÷ 7

= $1.57

Hence, the cost of the blueberry packing be $2.75 and the cost of the strawberry topping be $1.57

Leg =7, leg =24 what's the length
TEA [102]
(assuming this is a right triangle)
This is a Pythagorean triplet.
The hypotenuse is 25.

7, 24, 25

You can solve this using the Pythagorean Theorem, a^2 + b^2 = c^2
Where a and b are the legs and c is the hypotenuse, or longest side. 
We have that the two legs are 7 and 24. Plug these in for a and b.

Plug in values 7 and 24 for a and b.
7^2 + 24^2 = c^2

Simplify 7 squared and 49 squared
49 + 576 = c^2

Add the numbers
625 = c^2

Square root both sides
25 = c

So the hypotenuse, or the third side, is 25. :)<span />
