Answer: 16 units
Step-by-step explanation: adding the perimeter sides to get the perimeter of triangle ABC would be 4.1+6.1+5.8 = 16
Assuming your equation is: -2/5n = -30
-2/5n = -30 <- We get rid of the "/5n" by multiplying each side by 5n
-2 = -30 * 5n
-2 = -150n
-1 = -75n
75n = 1
But this doesn't match up with any of your answers, so if you wouldn't mind giving me the equation again, i'll work it out
Answer:
3(x-2)(x+5)
Step-by-step explanation:
1. Factor out common term 3
3(x^2 +3x-10)
2. Factor (x^2 +3x-10)
3(x-2)(x+5)
Answer:
a
Step-by-step explanation:
(3x-14)+9x=90, thus,
((3x-14)+9x)+90=180
90+90=180
