Answer:
17.5
Step-by-step explanation:
The area of a triangle is (height*base)divided by two
(the eight is really unnecessary)
so 7=base
8=height
7*5=35
35/2=17.5
Well first off what do you think the answer is, ill check it and if its wrong then we will work from that
Is 40 the correct answer is c
Answer:
for the 1 and 5/6, place it at the line before 2 and for 2 and 1/3, place it at the 2nd line past 2
2x^2 - 2x - 40 = 2x^2 -10x + 8x - 40 = 2x(x - 5) + 8(x - 5)
= (x-5)(2x+8) = 2(x-5)(x+4)
