Answer:
11 cm, 19 cm, 27 cm
Step-by-step explanation:
Triangles have 3 sides and perimeter is the sum of all side lengths. So the equation is x + (2x-3) + (2x+5) = 57.
x + (2x-3) + (2x+5) = 57
x + 2x - 3 + 2x + 5 = 57
x + 2x + 2x - 3 + 5 = 57
5x + 2 = 57
5x = 57 -2
5x = 55
x = 11
Now that we know the value of x, we can figure out the side lengths. The first side (x) is 11 cm long, the second side (2x - 3) is 19 cm, and the third side (2x + 5) is 27 cm long.
Simplify 9i(2+3i):
9i×2=18i
9i×3i=27i
18i+27i
Answer:
inequality form: w<-1
interval notation: (-1)
if this is not what your looking for then this might help
53w+13<55w+16
get w to one side
subtract 53w from both sides
13<3w+16
get 3w by itself
subtract 16 from both sides
-3<3w
divided both side by 3 to solve for w
-1<w
or w>-1
i hope this helped
and if it helped plzzzz mark as brainlest im trying to level up thanks

Step-by-step explanation:
X2 - 16, is the answer. The first one.
x^2 - 16 = (x)^2 - 4^2, difference of two squares :)
