what do we need to know:

the radius of the semi circles;

the area of:

purple region = area of a circle = pi * r^2;

green region = base * height;

what we know:

the base, 28m;

what the sum of the two diameters is, 28;

the length of a single diameter, 14;

what we can assume:

the two semi-circles are equal, as otherwise i cannot see a way to answer this;

the radius of the two semi-circles, 7m as the two diameters = 28, & d/2 = r

what does that mean:

the height is 17m

green region area = 476 m^2

purple region area is = 153.96 m^2

5x−2.5+6x−3= ___ (2x−1)

LiRa [457]

Answer:

5.5

Step-by-step explanation:

So, this is a simple factoring problem. The answer is 5.5(2x-1). So, heres how we get that answer.

So, factoring is basically breaking down the problem into smaller parts. So once we simplify the problem, we can factor it.

Simplify by combining like terms: 5x+6x= 11x and -2.5-3=-5.5

Now we have 11-5.5=?

so, we need to have (2x-1) in our answer because the problem asks for that in the answer.

We need to find a number that satisfies the equation and answer

so, 5.5(2x) is 11x, and 5.5(-1) is 5.5.

5.5 satisfies the equation, therefore is the answer

Answer:

answer is $330

Step-by-step explanation:

If you are ever dealing with percentages always put them into a decimal itll make things a lot easier

how you do that is 55/100 which is 0.55

then just multiply by the original number

0.55 times 600 which is 330

hope this helped

Answer:

(See explanation for further details)

Step-by-step explanation:

a) Let consider the polynomial $p(x) = 5\cdot x^{3} +2\cdot x^{2} - 6 \cdot x +17$ . The polynomial is in standards when has the form $p(x) = \Sigma \limit_{i=0}^{n} \,a_{i}\cdot x^{i}$ , where $n$ is the order of the polynomial. The example has the following information:
