That little squaer angle means right angle or 90 degrees
the black line and the red line cross
therefor the oposte angles are eqal measure
7x=90+x
solve
minus x
6x=90
divide 6
x=15
x=15
Answer:
(n- 2/3)²
Step-by-step explanation:
- <em>Perfect square trinomial is: </em><em>a²+2ab+b²= (a+b)²</em>
We have:
It can be put as:
Here we consider n = a and -2/3 = b, then
Now we add 4/9 to a given binomial to make it perfect square:
- n² - 2×n×3/2 + 4/9= (n- 2/3)²
So, added 4/9 and got a perfect square (n- 2/3)²
1 lap to ten minutes or 1:10 due to the fact that it takes ten minutes to run one lap. hope this helps, have a nice day :)
The total price for the gallons of paint will be 35.75p
The total price for the rollers will be 6r
So the equation if the customer have 190 will be
price for gallons of paint + price for rollers = 190
35.75p + 6r = 190
<em>(This is the equation)</em>
