The answer is D. 3.3x2 and 2.75x2 then add the answers together.
Hello from MrBillDoesMath!
Answer:
See Discussion section below
Discussion:
2x^2 + 5x + 3 = (2x+3)(x+1) which is Choice 3
3x^2+10x+4 =-1/3 (-3 x + sqrt(13) - 5) (3 x + sqrt(13) + 5)
I don't think any of the provided choices are right!
8x^2+10x-3 = (2x+3)(4x-1) which is Choice 2
6x^2-7x-4 = -1/24 (-12 x + sqrt(145) + 7) (12 x + sqrt(145) - 7)
I don't think any of the provided choices are right!
2x^2+x-28 = (2x-7)(x+4) which is Choice 2
Thank you,
MrB
Answer:
Since a fraction represents a division, we should do that division to know what the value of a fraction is. The larger numerator, the larger the value of the fraction will be; and the larger denominator, the smaller the fraction will be. ...
Step-by-step explanation:
A = pi r^2
A = 5^2 pi
A = 25 Pi
so semi-circle = 25 pi / 2
answer is a) 25 pi / 2 m^2
The easiest to find equivalent fractions is to multiply both the numerator and denominator by the same integer.
For Example, an equivalent fraction for 9/15 is 18/30. I got this answer by multiplying 9*2=18 and 15*2=30.
Another equivalent fraction for 9/15 is 27/45 because 9*3=27 and 15*3=45.
******Note
Just make sure that you always multiply the numerator and denominator by the same number, or else your fractions won't be equivalent!!
