Lets factor 8x^2 - 10x - 25
= 8x^2 -20x + 10x - 25
= 4x(2x - 5) + 5(2x - 5) 2x-5 is common to both parts so factors are:-
= (4x + 5)(2x - 5)
So its C
Answer:
156m^2
Step-by-step explanation:
label the shapes A and B) triangle=shape b and rectangle=shape a
shape a)10x12=120m^2
shape b)(12x6)/2=36m^2
add the values of shape a and b together to get the area of the shape)120+36=156m^2
