Answer:
7
Step-by-step explanation:
the square root of 49 is 7 since 7 x 7 = 49
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
Sin 167 = 0.22495
cos 107 = -0.29237
cos 167 = -0.97437
sin 107 = 0.95630
(sin 167)(cos 107) - (cos 167)(sin 107)
(0.22495)(-0.29237) - ( -0.97437)(0.95630)
= 0.86602
hope this helps :)
Ok so i just did 56/14 and got 4. So this means 14 goes into 56 4 times, so now i did 4 x 2 and got 8. So the answer is 8 free cones.
