Since you can carry 0 boxes but max is 10 and you cant carry 2/3 of a box or a square root of a box, they have to be whole boxes (whole integers)
Answer:
<span>x=9</span>
Explanation:
Substitute the y value:
<span>2x+<span>(3⋅6)</span>=36</span>
<span>2x+18=36</span>
Subtract 18 from both sides to isolate the <span>2x</span>:
<span>2x=36−18</span>
<span>2x=18</span>
Divide both sides by 2 to get x on its own:
<span>x=<span>182</span></span>
<span>x=9</span>
Thus, we have our answer.
The equation for a circle is (x-h)^2+(y-k)^2 = r^2
The h part in with the x is your x coordinate and the k part in with the y is your y coordinate. The r stands for the radius but be careful you have to square it.
so:
(x-(4))^2 +(y-(6)^2 = 16
I like to add the parenthesis around the "plugged in" numbers to help me remember negatives if I have any. <span />

Hence, the area is 36 sq. inches
Answer:
One root is 90 degrees or π/2 radians.
Drawing a graph we get all the roots:
nπ and π(n - 1/2)
Step-by-step explanation:
Sin^3A.cos A + Cos^ 3 A = Cos A
Divide through by cos A
sin^3A + cos^2A = 1
sin^3 A = 1 - cos^2 A
sin^3 A = sin^2 A
sin A = 1
So one root is A = 90 degrees or π/2 radians.
Checking this result:
(sin 90^3 * cos 90 + (cos 90)^3 = 1 * 0 + 0 = 0
cos 90 = 0
So this is correct..
