3x - 5 = 2x is the equation
The sup is 20 cm in total in square it is route 20 which is 10x2 so if its 1.50 dhs per sqm it will be 3 x 10 which is 30 dhs
So 30 x 4 is 120 please mark as brainliest
Answer: 
<u>Step-by-step explanation:</u>
The formula for factoring a cubic is:
a³ + b³ = (a + b)(a² - ab + b²)
f(x) = x³ + 3³
= (x + 3)(x² - 3x + 9)
To find the zeros, set each factor equal to zero and solve.
0 = x + 3 0 = x² - 3x + 9
-3 = x use quadratic formula

Answer:

It lines up right at the, 2 1/2 inches mark so i believe that is your answer!

1) Let's simplify those expressions making use of exponents rules:

Note that the exponent outside the parenthesis is 'distributed' over each term inside.
2) Similarly for the second expression we can state that:
