Mathematics
1 answer:
Ad libitum [116K]3 years ago
5 0

Answer:

1,728cm square

Step-by-step explanation:

Surface area=sum of all faces of a polygon

Let's do the biggest ones: 32•20=640

32•16=512

Now the rest:

12•32=384

16•12=192 192÷2=96

16•12=192 192÷2=96

Now add it all up: 640+512+384+96+96=1,728cm square

Simplify the following 3√28-5√63+4√112
alexandr402 [8]

7√7

using the ' rule of radicals '

• √a × √b ⇔ √ab

simplifying the radicals

√28 = √(4 × 7 ) = √4 × √7 = 2√7

√63 = √(9 × 7) =√9 × √7 = 3√7

√112 = √(16 × 7 ) = √16 × √7 = 4√7

substituting into the expression

3(2√7) - 5(3√7) + 4(4√7) = 6√7 - 15√7 + 16√7 = 7√7

Write the quadratic equation in general form and then choose the value of "b."
eduard
The answer is b. 11. 

You can find this by multiplying the two parenthesis together. In order to do this, you can use a multiplying process known as FOIL (First, Outer, Inner, Last), where you multiply parts of the parenthesis in this order to make sure you do so properly. 

First Numbers:
2x * x = 2x^2

Outer Numbers: 
2x * 6 = 12x

Inner Numbers: 
-1 * x = -1x

Last Numbers: 
-1*6 = -6

Now place them all in that order and simplify. 
2x^2 + 12x - x - 6 ---> simplify x terms
2x^2 + 11x - 6

Since the middle term (the one with the x value) has a coefficient of 11, that gives us a b value of 11.

(e+3)(e-5) expanded and simplified
Zarrin [17]

Step-by-step explanation:

(e + 3)(e - 5) \\ e \times e + e \times  ( - 5) + e \times e + e \times 3 \\  { e}^{2}  + ( - 5e) +  {e}^{2}  + 3e \\  {2e}^{2}  + ( - 2e)

In this type of math equation, you have to multiply all members from the first part with the second part.

Expanded:

e \times e+e \times (-5)+e \times e+e \times 3

simplified:

{2e}^{2}  + ( - 2e)
