To solve this you would have to do 10x/10=20/10. 20/10=2. Therefore, x=2.

U divide 10 both sides so it will be 10x/10=20/10
then x=2

Answer: 222cm

Step-by-step explanation:

To find the area of this composite shape you will have to split them into 2 shapes; a rectangle and a triangle.

To work out the area of the rectangle you have to do 15×12= 180

Then, to work out the area of the triangle, you use the formula base times height divided by 2.

7×12=84

84÷2=42

Then to work out the total area of both the rectangle and the triangle, you have to add the area of both.

180+42=222cm

Hope this helps :)

SOMEONE PLEASE JUST ANSWER THIS FOR BRAINLIEST!!!
stiv31 [10]

ANSWER

a=-2, b=3

EXPLANATION

The given equation is

(a {x}^{2})( - 6 {x}^{b}  ) = 12 {x}^{5}

Recall that:

{a}^{m}  \times  {a}^{n}  =  {a}^{m + n}

We simplify the left hand side to get:

- 6a {x}^{2 + b}  = 12 {x}^{5}

For this equation to be true, we must have:

-6a=12 and 2+b=5

This implies that,

a=-2 and b=3

If a paint can holds 2.5 litres, whats the radius of the can if it has a height of 20 cm?
Sloan [31]
Hello!

2.5 litres = 1,000 * 2.5 = 2,500 cubic cm

 

volume = π * radius2 * height

  2,500 = π * r2 * 20


2,500 / 20π = r^2


(Square Root of) 2,500 / 20π = r^2


6.307  <span>centimeters </span>= r (Radius)

 Hope this Helps! Have A Wonderful Day! :)
