Which equation is equivalent to 3[x + 3(4x – 5)] = 15x – 24?

makkiz [27]

Hello from MrBillDoesMath!

Answer:

x = 7/8

Discussion:

3[x + 3(4x – 5)] = 15x – 24 =>

3x + (3*3)(4x-5) = 15x - 24 =>

3x + 9*(4x) - (3*3)*5 = 15x - 24 =>

3x + 36x - 45 = 15x - 24 => (add 24 to each side)

3x + 36x - 45 + 45 = 15x - 24 + 45 =>

39x = 15x + 21 => (as 45-24 = 21)

39x-15x = 21 => (subtract 15x from both sides)

24x = 21 =>

x = 21/24 = -7/8

What is the area of the shaded region and the circle inside?

$r=20,1m+13,2m=33,3m$
$A_1=\pi r^2$
$A_1=33,3^2\pi$
$A_1=1108,89\pi$

What is the area of the circle inside?

$A_2=20,1^2\pi$
$A_2=404,01\pi$

What is the area of the shaded region?

$1108,89\pi -404,01\pi =704,88\pi$
$704,88\pi \approx 704,88*3,14\approx 2213,3232\approx \underline{2213,32}$

The answer: 2213,32 :)

7x to the power of 2 is a what is it<br>a) monomial<br>b) binomial<br>c) Trinomial

Sedaia [141]

You can use the prefixes to figure this out:
Mono: one
Bi: two
Tri: three

So, because there is only one term, it is a monomial.
