Choices A, C and F work. This is because when in radical form, you may dive or subtract as long as you keep the sign. The square root of 9 is 3 and the square root of 4 is 2. When you solve it, the answer is 6. Hope this helped!
Answer:
Geometric sequence
Step-by-step explanation:
According to the scenario, computation of the given data are as follows:
Leaves on tree this year (a) = 500
Rate of increase in leaves per year (r) = 40 % or 0.4
Let n be the number of years.
So we use exponential growth formula, i.e.
f(n) = a(1+r)^n
by putting the value, we get
f(n) = 500 ( 1+0.4)^n
or f(n) = 500 (1.4)^n
So, the common ration is 1.4.
Thus, it shows a geometric sequence.
Answer:
6(x+3)
Step-by-step explanation:
6x+18
6*x + 3*6
Factor out a 6
6(x+3)
30°
Here's why:
Using the well-known Pythagorian theorem we can reckon how long the hypotenuse is:
c^2=6^2+36*3 -> c=12
Knowing that sin(a)=a/c=6/12=0.5 the measure of the angle in degrees is 30°
