The answer for A would be 8.5 because if you use a^2+b^2=c^2 you would have 12^2 which equals 144 and you would divide that by two to get 72 and then take the square root to find the side length
The answer for be would be 45 because the sum of all angles in a triangle is 180 and you already know one is 90 and 180-90=90 and because this is an isosceles triangle you know the two bottom angles are equal so 90/2=45 <span />
Answer:
yes it is
Step-by-step explanation:
To find the slope, use the rise/run technique with rise as the difference in y-coordinates and run as the difference in x-coordinates. So, the rise is 6 units and the run is 3 units in this situation. Now simply put it as a fraction: 6/3, which can be simplified to 2/1, or 2.
Answer:
(2x+1)(5x+3)
Step-by-step explanation:
'split the x-term and factorise by grouping
10x2+5x+6x+3←(5x+6x=11x)
5x(2x+1)+3(2x+1)
factor out (2x+1)
(2x+1)(5x+3)
⇒10x2+11x+3=(2x+1)(5x+3)
plz mark me as brainliest if this helped :)
