The above expression is not in its simplest form, and we need to simplify it, that is what asked in the question.

Given equation,

(9 {x}^{2}  - 3x + 7) + ( - 3 {x}^{2}  + 2)

First of all, let's open the parentheses to combine the like terms for simplifying.

9 {x}^{2}  - 3x + 7 - 3 {x}^{2}  + 2

Arranging the like terms, x² with x², x with x and constant terms near to each other.

9 {x}^{2}  - 3 {x}^{2}  - 3x + 7 + 2

Simplying further,

(9 - 3) {x}^{2}  - 3x + 9

6 {x}^{2}  - 3x + 9

So, the correct option is C

Is 976 -522 more or less than 400? Explain how you can tell without actually subtracting.
liq [111]
You can round 976 to 1000 and 522 to 500. So it would be
1000 - 500 = 500. The answer you would get after subtracting 976-522 would be more than 400 if you round it.

The area of the circle is 144π m2<br><br> What is the diameter of the circle?
Over [174]

Answer:

Step-by-step explanation:

Remember that

Area of Circle = \pi r^2

\pi  = pi \\r = radius

They told us that for this circle, the area is 144\pi  m^2

If you put it back into the formula for area of a circle we get:

Area of Circle = \pi r^2

144\pi = \pi r^2

Divide both sides by \pi.

144 = r^2

Now we want to solve for r (r = radius).

You need to square root each side

\sqrt{144} = \sqrt{r^2}

12 = r

So now we know the radius, r = 12 metres

Also remember that

Diameter = 2r

So,

Diameter = 2 times 12 = 24 metres
