Answer:
22.5
Step-by-step explanation:
Hey there! first, we find 25% of 30 which equals 7.5 then we subtract 30 - 7.5 which is 22.5
3x² (6x² - 13x - 5) =
3x² (2x - 5) (2x+1) .
N= -4
-4/2+5=3
-2+5=3 you have to subtract the 5 from three first and then multiply the answer by 2 to get n
I think the answer might be x=24
Ok, so remember
the legnth of the longest side must be LESS THAN the sum of the measures of the other 2 sides
if no longest side (becasue it has 2 longest sides or 3 equal sides), then it can form a triangle
so the longest side is 36
36 must be less than the sum of 15 and 20
36<15+20
36<35
false
therfor it cannot form a triangle
try it yourself, you cannot connect them that way
