Ur answer is 6 (20+20+20+20+20+20+21+21+21+21+21+21+21+21+21+21+21+21=372) and they need at least 362 hope this helps I'm pretty sure this is right sorry if it's wrong but it seems right to me
Answer:
3
Step-by-step explanation:
Note the general factorisation of a difference of 2 squares is
a² - b² = (a + b)(a + b)
Given
(- 5x - 3)(- 5x + ?)
Then ? = 3 so that the complete factors are
(- 5x - 3)(- 5x + 3)
<span>equilateral triangles, squares, and regular hexagons</span>
You need to find out how much it costs to wash one car, so:
3×=13.50
Divide both sides by 3.
x=4.5 per car.
Now multiply 4.5 by 25 which should give you $112.50
<span><span><span>2<span>x^3</span></span><span><span>−2</span><span>x^2</span></span></span>+<span>3x</span></span>+<span>1 is the reduced answer</span>
