It's more than 3600, so its greater than 60.
it's less than 4900, so its less than 70.
a no.'s root can end with six if the no. ends with 4 or 6.
so the no is either 64 or 66.
Now if it's 66, the square must be greater than sq of 65.
65 sq= 4225
the given no. is greater than sq of 65.
Therefore the number is 66.
⇒ 7<span>/2 as a fraction
Solutions
To convert 7/2 into a mixed number you have to find how many times 2 goes into 7.
Calculations
2 x 1 = 2
2 x 2 = 4
2 x 3 = 6
2 goes 3 times in 7
We cant do 2 x 4 because it would be bigger then 7

Answer:
(d) (-2, 6)
Step-by-step explanation:
We can rewrite the function using vertex form.
f(x) = (x^2 +4x) +10
f(x) = (x^2 +4x +4) +10 -4 . . . . . . . add and subtract (4/2)^2
f(x) = (x +2)^2 +6
Compare to vertex form:
f(x) = (x -h)^2 +k
we see that (h, k) = (-2, 6) . . . . the vertex
_____
<em>Additional comment</em>
The value added and subtracted is the square of half the x-coefficient. Inside parentheses, that value "completes the square". Outside parentheses, that value ensures the overall function remains unchanged.
Answer:
The brother is 36 years old.
Step-by-step explanation:
b = brothers age
b - 18 = 18 | Given
b = 36 | Add 18 to both sides to cancel out -18 and get his age.
Answer: 5th week
Step-by-step explanation:
E= -12w+568
520= -12w+568
520+12w=568
12w=48
w=4
4+1=5th week
