The area of a rectangle is it's length times it's height. We are given polynomials for these values, so we can multiply them using the FOIL method to find the area.
FOIL stands for Firsts, Outers, Inners, Lasts. This means we multiply the first term of each polynomial together, the outer terms together, the inner terms together, and the last terms together.
(2x+5)(x-2)
The first terms are 2x and x, the outer terms are 2x and -2, the inner terms are 5 and x, and the last terms are 5 and -2:
2x^2 - 4x +5x - 10
Combine like terms:
2x^2 + x - 10
The third option is the correct answer.
9,11,13,20
20 -9 = 11
Range: 11 so its not 17
11 + 13 = 24
24/2 = 12
Median: 12 so its not 10
9+ 11 + 13 + 20 = 53
53/4= 13.25
Mean: 13.25 so its not 12
IQR: 6.5 so its not 7 or 12
Answer:
4 is the correct answer of the question
Answer:
I think the answer is t=p/ir
Answer:
Step-by-step explanation:
As we can see in the figure that
The R, S, T ,and Q are the points on the circle O.
Also
The measurement of the circular arc is equivalent to the measurement of the angle at the center of the arc
So by this
m(major arc RQ) = m(∠QOR)
So,
And as we know that
All angles sum = 360°
Therefore
