Answer:
see explanation
Step-by-step explanation:
the sum of the lengths of any two sides of a triangle is greater than the length of the third side.
if the sides are a, b, c , then the following must be true
a + b > c
a + c < b
b + c > a
for the 3 sides to form a triangle
2 n - 2 = n - 38
Two fewer than "a number doubled"
2n-2 = n-38
(2x+5y)(2x+3y)
=(2x)^2 + [5y+3y]2x + (5y)(3y)
=4x^2 +16xy + 15y^2
B
3*5 is 15 and since its a negative 5 your answer will be negative
Add 2y to both sides
12x-2y+2y= 8+2y
12x = 2y+8
Divide both sides by 12
12x/12 = (2y+8)/12
x= 1/6 y + 2/3
I hope that's help !
