Answer:
B. No solutions
Step-by-step explanation:
If you try to simplify it, you get
2x-2x = -5-5 or
0 = -10
Which will not be true for any value of x.
If you would draw the lines y = 2x+5 and y=2x-5, you'd see two parallel lines that never intersect. The intersection would be the solution, but, it never happens.
Answer:
54 cm
Step-by-step explanation:
The area (A) of an equilateral triangle is
A =
( s is the side length ) then
= 81
( multiply both sides by 4 to clear the fraction )
s²
= 324
( divide both sides by
)
s² = 324 ( take the square root of both sides )
s =
= 18
Thus
perimeter = 3 × 18 = 54 cm
Answer:
THE y eso que es?
Step-by-step explanation:
Very confusing math that focuses on graphs, equations, inequalities, quantities. Algebra uses a lot of symbols, multiplication and calculations.
Hopefully this helps!
