60/45 = $0.75
It costs $0.75 to make each valentine so if they were sold for 75 cents then that would result in a profit of zero if all the valentines were sold.
1.your going to look at the squares in the background , now on the bottom they are six squares with a line in the middle. your going to put a dot or line on the bottom line of the triangle on each squares ending point (like if your creating a ruler without the tiny lines)2. Ok now if you take the line in the middle( thats all ready in the triangle) you can say that makes to right angle triangle's ,so the one on the left and the one on the right now the one in the left has three squares ( cause remember you had 6 squares but the line in the middle of the triangle splits the triangle into 2 right angle triangles which makes it 3) your going to take each dot and bring it to the top or head of the triangle and you should be done
hoped it helped !!!
Answer:
The roots are real and unequal (3, -3)
Step-by-step explanation:
x²-9=0
ax²+bx+c=0
Comparing we get,
a= 1
b= 0
c = -9
Determinant: b²-4ac
= 0² - 4(1)(-9)
= 36>0
D > 0
Therefore, the equation has real and unequal roots.
Algebraic identity:
x² - a² = (x-a)(x+a)
Using this identity
x²-9 = (x+3)(x-3)
Roots are 3 and -3 which are real and not equal to each other
Hope this answer helps you ..
